Almost 2 years ago, I saw a video that Steve Mould made about something called an atomic trampoline and the moment that I saw it, I really wanted to one. The only sad part is that it is now impossible to buy one, so instead, I decided to just make one myself.

[@nicholasdowns3502]

As a welder (mainly tig) a couple of major things that I noticed is that your tungsten rod got contaminated with your metal pool. A contaminated tungsten will tend to create a colder and less controllable arc as well as contaminating your metal puddle. I don’t know if this could apply to your situation, but when welding stainless (and steel) the tungsten is sharpened to a point to improve penetration of the metal (might melt the bottom of the puddle better). The final trick I can recommend is a tungsten alloy, a 2% thoriated tungsten is the industry standard for a good tungsten because it makes a more stable arc (slightly radioactive especially when ground, produces primarily alpha particles which do not penetrate skin) TLDR: -contaminated tungsten = contaminated alloy -contaminated tungsten creates poor arc -sharpening tungsten to point increases penetration (seems I may be incorrect about this, but it may be something to try still) -other tungsten alloys can result in a more stable arc (safer alternatives are available to thoriated, resulting arc stability will vary)

[@YungChristx]

[@djelilikejam]

the second i heard “arc melter” i was like “awwwwwe yeeeeeahhhhh” lololololol

[@eli84360]

The tungsten is sharpened to influence the arc cone shape. The angle of sharpening affects penetration. A 60° grind will have far better penetration with a small puddle than 15° with a wide puddle

[@theexchipmunk]

Yeah, a thought I had while watching was that the electrode most likely was a main point of failure, just going of the power supply. It´s one of those small things that often is cheaped out on, even if compared to the main device not being all that expensive. On the pointed electrode I have to disagree tho. For welding that is wanted, to focus the arc and increase penetration, and reduce the affected area and speed up the very localised melting. But there a more spread heating with less of a short term heating is required. There is less of a limit to how long the melting takes, and more of a requirement that it happens in as much of the material possible. So while less speedy localised, a less focussed electrode is probably better for this application.

@NileRed when I got to graduate school, there had been a terrible accident with an arc melter. The failure was the pressure relief valve on the chamber. Argon gas was heated inside the chamber, and without a functioning relief valve, the pressure increased to the point that the glass viewport window exploded, throwing glass splinters into the head of the person who was using the equipment. Please make sure your system has a double, redundant, pressure relief valve. And thanks for the amazing content.

The problems with the mold were due to cold runs: the metal solidified too quicklyso it only partially filled the mold before solidifying at the inlet. The principle is, that the metal on top is completely molten but doesn't go in due to surface tension, that only happens when the mold is vaccuumed, The metal then blocks the narrower outlet solidifying there first due to the high surface to volume ratio coolng there quickest, which is intented. At that point the mold should be under vacuum, as the outlet is then blocked. It might help to clean the faces where the mold separates to reduce argon drawn in through the gap, it seems the mold is pressed together due to the conical form, so maybe pushimg it down a little when installing it helps too. Heating the metal longer did two things: it ensured the metal is completely molten, which is necessary for the mold to work, and it likely preheated the mold a bit, delaying the inlet freezing off. I'm not sure why the outlet is at the lowest point, having it go out at maybe the 10 o clock position may actually work better, so you can draw vacuum until the form is (nearly) filled, but there's not enough space to route it to the bottom anyways (it has to be where the mold separates, as it'll at least partially fill with metal). The uneven surface is likely due to shrinkage (volume loss during solidification), as the inlet is frozen off and no more liquid metal can flow in to compensate for the volume loss (feeding). One could experiment with a slightly larger inlet, allowing better filling and maybe a bit more feeding, it may also depend a bit on the alloy and it's surface tension what diameter is best. Since the mold is an inset you might try to have another one made, but that'll still be an expensive part.

[@jaskaran_singh_saini]

Love to see this video on metallic glasses, the materials that I did my PhD on and even more happy to see that the papers Nile highlighted in the video are from my PhD advisor, his PhD advisor, my postdoctoral advisor and other collaborators. It is not common for youtubers to delve so deep into materials science, especially into advanced metallic alloys such as Metallic Glasses. The amorphous nature of MGs is what gives them that bouncy nature. Metallic glasses have a high coefficient of restitution that causes the ball to bounce. Btw, you don't need toxic metals like Beryllium or expensive metals like palladium to make these in large sizes. You can make them with much cheaper, non-toxic metals like copper, aluminum, zirconium like what I invented during my PhD. I have 2 worlds records for the biggest copper & Hafnium based metallic glasses ever produced. We've produced these in the size of the steel cylinders Nile was using in the video (in both diameter & height) in my lab so you can imagine how big we can make them. MGs were invented by my academic great grandfather in the 50's but we only started making them in large sizes 90's onwards. The metallic glasses I invented have been the most recent major advancement in this area. There were a few things Nile could’ve done better to make better disk samples such as used ultra-high purity Argon, slowly increased the arc power rather than expose the arc to all metals at once; let the low melting temp elements melt and combine first before the high temperature ones, cleaning the copper mold and crucible after every run to prevent contamination etc. The thing Nile mentioned about the metallic glass not being safe to grind and polish because of beryllium is not true. Once the beryllium has been absorbed into the metal matrix, it is very safe. I literally produced thousands of these metallic glasses in my lab during my PhD, and some in very big sizes and they are all safe. For anyone trying to get their hands on these including Nile, the best way is to reach out to universities, labs, some small companies and people working on metallic glasses. They’d be happy to set you up with some samples or at least tell you the best way to produce them although I have to give it to Nile, he is 75-80% there. Also, you don’t need that much of Titanium for gettering. 5-6 pellets are enough.

It's fascinating to see how your work on metallic glasses (MGs) is being highlighted in public forums! As an electrical engineer, I'm particularly intrigued by the potential applications of MGs in our field, especially given their unique properties like high strength and elasticity. Seeing the developments from your PhD and collaborations with other leading experts, it's clear these materials have a lot to offer. I was wondering about a few aspects: From your experience, how do metallic glasses hold up under long-term stress or repeated thermal cycling? Are there specific applications where their durability has outperformed conventional materials? Silicon transistors face challenges with thermal stability at high temperatures, leading to performance degradation. Could the amorphous structure of metallic glasses provide better thermal stability and potentially enhance the reliability of transistors in high-temperature environments? In transistor development, the dielectric properties of materials are crucial. Have there been investigations into the dielectric behavior of metallic glasses? Could they potentially serve as effective gate dielectrics or insulating layers in MOSFET designs?

Two things make sense to me regarding the mold; First, I'd have put the vacuum port off center from the inlet port / "pouring cup" so that the melt will pool from the bottom up. Second, would it be off protocol to shut the cooling water off shortly before you plan on pulling the melt into the mold, then turn it back on when the pull pour is complete. This would slightly increase the time the pour is flowable.

I'm a grad student in the last year of my physics PhD working in a condensed matter physics research lab.

I'm really impressed you managed to get such good results by teaching yourself! That said, watching your video I saw there are still a few mistakes, things like not grinding the arc tip to the right shape, not moving the arc correctly, not arcing for long enough, etc. I know the project is done, but I imagine you'd want to keep using the system in the future, I'd be happy to share some tips, tricks, and stories if you're interested!

Having worked in the aerospace industry we did grind beryllium using oil as it would not evaporate leaving dust. I also use electron guns in a vacuum chamber with various chemicals, with metal materials you want to heat slowly as some materials have trapped air pockets. Blasting at full power I would talk you out of. Slow and steady. When you have different melting points the lower ones will stabilize the environment. I liked that you placed your electrode at an angle causing the pool to rotate.

[@platinumsky845]

Would the air pockets be as much of an issue with the extremely high purity metal samples he has?

[@spartan456]

@@platinumsky845 The purity of sample is just how much extra stuff is in it, like specific contaminants. No matter what you are most likely going to have small, microscopic air bubbles trapped in the metal as it cools and solidifies, specifically from outgassing. I don't work with welding, but I've done a LOT of stuff with solder over the last 10 years with electronics repair, and a very common issue with that is planar microvoids. These are literally microscopic air cavities that form in solder as it solidifies, resulting in a weaker joint that can easily be broken from mechanical stress. These voids usually form as a result of flux and outgassing. Regardless of alloy composition, I have a feeling this is something that would be an issue with any kind of molten metal. I have a feeling eutectic alloys would especially have this issue. To handle outgassing you'd wanna keep the metal molten long enough to let the air bubbles escape. No matter the purity of sample, it still had to be melted and solidified in a mold at some point in the process to turn it into a sample. Even if done in a complete oxygen-free environment, it is entirely possible some of the shielding gas used could get trapped in the molten metal, and this gas would come back out (possibly violently) when the metal is melted. Basically, the purity of sample does not dictate whether or not it will have air bubbles. I don't know if Nile reads comments but if he happens to see this, I bet something that would greatly improve the quality of all cast metal projects would be to sand the surface of the molds he is using. I was surprised he did not do this. Sanding and polishing the surface of the mold would assuredly result in a much cleaner looking surface finish for your casted metal. A little wet sanding under the fume hood for the finished product would probably clean them up just fine.

[@acoral1035]

OMG this is metalic glass. My thesis theme. I have a few comments. 1) The main part is in cooling. The way of heating is actually mostly irrelevant 2) Each metal in alloy actually has its function in either achieving eutectic system, or controlling the diffusion field around potential crystalisation points, that can spoil the result 3) I believe some inconsistency you got ties to the fact the process is very sensitive to specific kinetic curves. This means the plot of temperature over time must be exactly the same to achive the same results 4) Mechanical treatment changes the midrange structures of the AMA. This can be exploited to create bigger chunks, but also it probably means that you have turned the upper layers of your disc into usual metal alloy by grinding it. 5) To check that what you have got is really a glass - you can try multiple experiments, it is not just about bouncieness, there are a lot of properties that are different for amorphous states. The simple one is probably exposing to fire - not the plasma from wielder, just usual fire. It usually has very low temperature at which it transforms into crystal, releasing a lot of free-volume. I would try to use a lighter on cut off chunks to see whether they'll start to cover in cracks immediately (you may see somewhat leaf-like structures on the surface just from a little of heat). 6) I've mostly worked with stripes, using spinnings and splatters, but I read some studies on volumetric samples, and saw a similar disk. It was created in a way more complex setup, with a more finicky slow cooling technique. It requires the process of monitoring the volume of plate for subcritical size crystals, and removing them physically during the cooling. The initial formula has to account for the loss of the material that will get crystallised and removed. It is way harder, but it gives you more traditional metallurgy control over heat curve, and it is possible to grow a disk of this size with such a process, while esuring it has a flat glassy surface (no post-processing).

Also 7) try to use FeAl 1:1 based alloys with low quantity admixtures. You can avoid much more toxic metals like beryllium.

Till I got to the beryllium part I was wondering how the heck an amorphous alloy can can cause asbestos-like mechanical damage. Beryllium isn't that uncommon in industry though, it shows up in specialty alloys and ceramics, I suspect this alloy isn't widely available in discs just because it's hard to work and there's not much industrial use for it, as far as I know most amorphous metal is in ribbon form and used for things like transformer cores.

Hi, a PhD material physics student doing MG-related research here. Metallic glasses are somehow very rarely talked about in yt educator space, so Im happy to see this and great job! I really think you should've tried some of those non-toxic bulk metallic glasses, you can definitely make some of these with this setup and the bounciness shouldn't be that much different in principle, since the energy normally escapes through formation of defects, but for MGs there aren't any defect forming mechanisms that are present in crystals - no vacancies, no lines, no stacking etc. So i am actually curious how different other MGs would be.

They would preform all operations cutting with as much oil as they could get on it taking really small cuts Ideally submergeing the part in oil. Then to gring or polish it was all done submerged in oil. Then the oil was safely disguarded after machining was complete. I would do more looking into it if you wanted to try and polish the discs to make them more perfect. I know my grandpa had a special box that would lock onto his milling machine that would allow him to fill it with oil then machine in there.

The Beryllium exploding during the melting process really looks like a gas explosion. My guess is that whatever impurities are inside the beryllium are heating up along with the rest of the metal, but evaporate at a temperature much lower than the melting point of the beryllium. With the rate at which this arc melter heats the metal, the evaporated impurities then want to quickly expand due to the heat, pressurizing and blasting open the beryllium nugget from the inside. This would also explain why some of the beryllium nuggets fared better than others: If a nugget's impurities are spread evenly, then the resulting gas bubbles are significantly smaller and might not be strong enough to blast open the rest of the nugget, while if the nugget happens to have a larger clump of impurities inside it, it will explode. Once the beryllium melts, the gas bubbles can leave the liquid without causing a mess, which is probably the source of the smoke. If you were to try making alloys with the arc melter again and can't somehow safely purify the metals further as with this beryllium, you might want to consider starting at the lowest power setting, and incrementally increasing the power and heating the metal as slowly as possible. This gives the metal slightly more time to adjust to the increased pressure of internal gas pockets and reduces the chances of bursting.

Having spent 10 years of my career in metallurgical and material sciences, I knew that this was going to be a very tricky project. It was apparent to me that after you had cast the disk, the vast majority of the issues you had related to the condition of the surface. If you had a laboratory bench grinder, it’s simple to polish these very flat. Also, if you were to lap them using a lapping machine, you would not need to use the glue and could have a better surface contact to the base material. I think you could easily double the bouncing time using this method. But I know you you’re not going to do that because that wasn’t the point of the video. Maybe it will be a good reference for you if you ever try to do another project like this. Glad you pushed through the issues and finish the project. Well done!

Didn’t he avoid grinding because of the Be dust?

[@nikkiofthevalley]

​@@hx5525Yep, but he did use sandpaper anyways for the glue at the end.

[@marshallwilliams4054]

@@hx5525 laboratory bench grinder is essentially a lapping machine that runs under a constant stream of water. There’s no dust. Most of the time, depending on the kind of material you’re grinding, the waste water can run directly into the sewer because it is nontoxic. In the US, specifically Texeas, the alloys he created would probably fall into that category

[@marshallwilliams4054]

@@nikkiofthevalley laboratory bench grinder can get much more flat. I suspect (but I’m not certain) a significant amount of mechanical energy is lost using the gluing method. Having two meeting services that are nearly perfectly flat lose much less energy.

[@bubbagump9118]

Excellent video!! I have a few follow-up recommendations: 1.) Use the vacuum pump to remove the air from the bouncy tube and see how much longer it takes to decay to a stop. 2.) If the bounce is caused by preventing defects from forming in the glass, they can still form in the ball bearing. I'd like to see a metallic glass ball dropped onto the flat metallic glass disk under a vacuum. Would be a great way to utilize a non-toxic metallic glass that you could then grind in a ball mill into a sphere. Alternately, use a ceramic ball from a ceramic ball bearing and see what you get. 3.) mount a sound coil onto the bottom of the disk assembly, and tune the frequency. In a vacuum, you may be able to get the ball to bounce perpetually. 4.) If you do get around to making a non-toxic disk, there are simple ways to polish the surface to a flatness below 2 light bands. That along with careful leveling should keep the ball from bouncing side to side and touching the glass tube.

My constant thought throughout the video: "Just don't use beryllium? You said yourself that there were a ton of different alloys, and nothing was ever said about this alloy being the best. No need to replicate steve's trampoline if you could simply beat it by far instead. So make all the non-toxic ones, test their trampoline-iness, and then use the best one." Also wonder why he doesn't make the bearing out of the same material, or if worse trampolin materials could even make for better bearing-materials due to how it interacts with the trampoline?

[@n30p47h1c]

You are also not realizing how much he makes per video...

[@antman7673]

The Plasma forms due to electricity. In the grand scheme of things, that is probably negligible. The machine is probably more expensive than the electricity it is using for a few experiments. If someone used 50 to 100 toasters at once, that would not be to too wild. (I am also just guessing the number of toasters 700W per toaster and not sure how much the welder uses) 100kW plasma torch costs 100 * price per kW. If you pay high german prices with 30ct per kW. That is $30 for an hour of use. $30/hour vs. $14k to buy the machine. That is almost 500 hours of use to be even.
