Episode 97: Titanium

[@bmobert]

First time listener, here. This was amazing and lovely. I knew materials science was intricate but I had no clue how intricate until now, when I got to hear two materials science nerds back-and-forth. Just brilliant! Subscribed!

[@TaylorSparks]

This makes me so happy to hear. Glad you enjoyed it. You are lucky, there are a backlog of another 96 episode you can listen to

[@DhruvJain_IIT_Indore]

Really interesting podcast, Learnt a new perspective to see Materials!!

[@TaylorSparks]

Thank you!!!

[@Rorschach1024]

I just found this podcast. Former ASM member before I retired from the oil production industry as well as steelmaking industry. And I am hooked. Thank you!

[@TaylorSparks]

@@Rorschach1024 that is so great. I'm so glad that you found us. Let us know if you've got a topic you want us to do in episode on

[@Rorschach1024]

@TaylorSparks i need to go back and see which ones you've already covered. My specialties were nickel alloys, super duplex stainlesses, and the welding and processing of them. TIG, EBW, specialty shielding gasses, EDM, etc.

[@LiquidMetalLab]

These podcasts make work fly by thank you!

[@TaylorSparks]

@@LiquidMetalLab thanks for listening! Share it with some friends to help us grow the channel

[@baderq8ty99]

first time listening to this channel, i got maybe 70% of what you were saying if i'm being generous to myself, sometimes adding images of things you're talking about for context would make it a lot easier to understand for material science newbies

[@TaylorSparks]

@@baderq8ty99 this is great feedback. We really struggled to find that line between depth and breadth. We want it to be accessible to everybody while still being interesting to people who work in the field

[@muskepticsometimes9133]

great show guys. I have 2 titanium implants 1) dental implant 2) device to plug hole between heart chambers

[@TaylorSparks]

It's a miracle material for bio applications

[@jinlongsu7308]

Titanium is a lovely material with superior specific strength, low density, excellent room temperature corrosion resistance and great biocompatibility. However, its limitation is also obvious: poor wear resistance, low thermal conductility (diffcult for machining) and way more expensive than steel and Al. I have studied on Ti alloys for 5 years, including both alpha, alpha+beta and beta alloys 😊. Wonderful video, very insightful! This could let more people to get to know titanium better.

[@TaylorSparks]

@@jinlongsu7308 so thankful for this insight

[@wingracer1614]

The low thermal conductivity is why it's not used in some places you would think it would be perfect. For instance, while titanium is used for some connecting rods in ICE engines (F1, Honda S2000 for instance) it is not widely used in performance engines specifically because of the thermal conductivity. It can cause hot spots in the bearings that breaks down the oil. Manufacturers are starting to figure out workarounds so it's starting to get used more but you would think it would have been common by now. But that can also be a plus in some instances. For instance the pistons in disc brakes. They don't need to be that strong so aluminum would be fine but the poor conductivity of titanium helps keep the brake fluid cool.

[@SirLaggsAlot]

Glad to have y'all presenting!!!

[@TaylorSparks]

Thanks dude, we put a lot of time and effort into delivering a really nice product. In fact, we had to record this episode twice cuz we weren't happy with the quality on the first time around

[@AeroAce_YT]

Another sleepy time podcast found! THANKS

[@taliemarais5417]

So I recently decided to start doing research on metalurgy and a comment on reddit sent me to this channel. I seriously got so so excited seeing just under a 100 videos about what I want to learn, I know this isnt really the entirety of metalurgy, but it's a good start for me. Do you have any suggestions on books I can read that can give me as much info on any subject of metallurgy. I know my question is vague, but any guidens would be appreciated.

[@TaylorSparks]

There are lots of great textbooks out there. Callister is a good place to start if you haven't studied materials and metallurgy. If you want one specific to metals then mittemeijer is a good book, but it's at The graduate level

[@adrianmateas1306]

Greatest gem I found this year Hope you get big enough for everybody to see all the cool material you have

[@TaylorSparks]

Help us share it so we can grow! Thank you so much!

[@jaewan234]

Favorite metal! Literally part of my body as a femoral implant. I also did undergraduate corrosion research on titanium alloys!

[@TaylorSparks]

Heck yeah!

[@bobbobberton]

KZbin algorithm blessed me with this one. Great content and instant subscribe seeing the treasure trove of videos on this channel. I'd love to see an episode on aluminum!

[@TaylorSparks]

@@bobbobberton yeah we definitely need to do an episode on aluminum. We need to reach out to some of the big companies in the space to see if they might sponsor it

[@bobopokomono-nu3gv]

great stuff. love the little bits of history and the amazing graphics

[@TaylorSparks]

Andrew makes the best art in the biz

[@Eristotle222]

Thank you so much for this podcast!!

[@TaylorSparks]

You're welcome! I'm glad you enjoyed it.

[@csours]

Alec Steele has a titanium "damascus" forging series that I found very interesting

[@joshuawinger7601]

Nice material (pun intended). Haha. I was hoping to hear about titanium's role in superconductors (NbTi) as well. Looking forward to future podcasts!

[@TaylorSparks]

@@joshuawinger7601 hi Josh!! We've got a miniseries on quantum materials and a dedicated episode on the series will be superconductors :) Hope oxford is treating you right

[@alan_clough]

Yo I was just "researching" titanium last night.

[@TaylorSparks]

Exquisite timing my friend.

[@vkaras6591]

You guys rock,!

[@matthewmesser7859]

Hello Prof. Sparks I just want to say that I have been deeply invested in the materialism podcast series and am looking forward to many more! Is there any books that you would recommend for someone with a passion in material science.

[@joshuahammer4454]

Thanks

[@TaylorSparks]

You're welcome!

[@acrashiscoming]

welcome to the metalverse

[@AdamBrusselback]

Good luck with the channel. Just ran across this video, liking the content.

[@TaylorSparks]

@@AdamBrusselback thank you so much. Share it around with any friends who might be interested.

[@SuperMan-uj7dh]

i like your podcasts a lot, but a suggestion is to make a few slides and present over it. This will be more intuitive instead of listening to people talk. Maybe a zoom meeting where we can see faces? That would be better!

[@TaylorSparks]

@@SuperMan-uj7dh yeah, we've thought a lot about adding a video component to the show. It might be something that we do in the future.

[@AvaBernards]

One of my favorite parts of titanium is the gorgeous oxide colors you can get by torching or anodizing it

[@TaylorSparks]

@@AvaBernards yeah, there are companies that explore colored devices by growing oxide films on it. 🍏

[@stevengill1736]

Titanium filings are also used in pyrotechnics - it makes beautiful sparks in star compositions.... Titanium tetrachloride makes white smoke in air and used to be used in the theater and special effects, but it's too corrosive for current use, though I found if one has ammonium hydroxide it can be placed next to the TiCl4 it doubles the amount of smoke and neutralizes the HCl produced by air moisture.

[@shaunybonny688]

Interesting, even more so because I work at a titanium melt shop. They shut down the Kroll process here in 2020.

[@TaylorSparks]

Wait, so what are you doing if not the kroll process?

[@Looser272727]

Following

[@TaylorSparks]

@Looser272727 thanks! Leave us an iTunes review;)

[@jbeason2929]

Great podcast even tho there was alot of terminology that went over my head. As a car nerd, I now need to look into why a company would use Titanium over carbon fiber or aluminum, if titanium is so difficult to work with and costs so much more.

[@TaylorSparks]

@@jbeason2929 thanks!! We try to avoid too much terminology. Something for us to work on. Thanks again

[@muskepticsometimes9133]

the Douglas DC6 was first commercial plane to use titanium

[@QuintusAndreus]

Avid listener. Thank you for your podcast. I do a lot of cold sprayed titanium for work. Cold spray episode soon?

[@TaylorSparks]

What company?? We should do an episode

[@hankhafliger482]

My sister herded her Valais sheep up at that sheep run in Sun Valley this year.

[@TaylorSparks]

@@hankhafliger482 No way! Andrew is your biggest fan. He loves that dog show

It's either a really impressively convincing AI podcast or a really badly edited human podcast.

[@TaylorSparks]

@@SakhiGuma687 yikes! We are humans 😔 How can we improve?
