Heat Treatment - Types (Including Annealing), Process and Structures (Principles of Metallurgy)

Heat treatment is one the most important metallurgical process in controlling the properties of metal. In this video we look at the types, process and structures.
Softening heat treatments include annealing and normalizing, and hardening heat treatments include quench and tempering, and age hardening.

[@ArcanePath360]

Finding this all so confusing. So is tempered steel just heated up to 650c and allowed to slow air cool? Or does it still need quenching?

[@arinurramdhani2798]

Thank you for the video

[@varasanisatish9866]

Superb video!! Kindly make video on how to oprate induction furnace and how to calculate scrape and alloying elements weights for making of desired steel.

[@m.e-mahdi5159]

You just saved my whole semester, kudos to you. My words can't appreciate enough about the content and the effort you put into it. I will take this for granted, as I had an argument with my welding professor about heat treatment affects on welding productivity and efficiency, he thought that quenching (water) is bad for the welding materials, as he said there are oxygen in water therefore it affects the weld and it makes it bad as it get corrosion, he was assertive that we should use normalize treatment rather quenching. Now, I have come to realize that my professor has got it differently, since according to this video, quenching is way more better in terms of strengthen, so if you don't mind answering me, would you please give me your thoughts on this matter?

[@zerotwosixty7416]

incorrect, quenching makes the weld more brittle.

[@zerotwosixty7416]

also the higher the strength the more brittle it is.’So a higher carbon metal such as cast iron is stronger but more brittle which is what you don’t want because it’s more prone to cracks. That’s why when a butt joint is welding you let it air cool before the bend test and not quench it.

[@wewillmakeyouaplaceforthew5793]

There is no such thing as better, both have their specific uses and advantages which depend upon your desired properties, and case.

[@kentuckyken6479]

Thanks for the very cogent explanation on what's happening in the annealing process. I hope you can help me with a problem that I can't seem to Google up an answer to. I accidentally left some brass (30% Zinc) for 30 min or so at 350 F. I need to know if that combination of time and temperature resulted in any significant annealing of that brass. If it did, I will have to throw out those cases and I don't want to unless I have to. Thanks in advance for helping a biology guy out who is definitely not a materials science guy.

Please sir can you explain the annealing temperature atomized iron powder with three zone and its hold time including cooling.

[@-KANE-]

Excellent video,

[@brianbabcock7272]

My idea is to mix powdered metals into forms and then heat or electro fuse into solid molds. The advantage is less over all work space and Less intense makes safer work and less likely for major catastrophe. Also smaller ovens, more specialized for each item will it work?

[@syafiqzainun7383]

[@MetallurgyData]

Hi Greg, thanks for your kind words. ASM heat treaters guide is a good resource. You might be able to find some specific material charts online for free

[@hassaanahmad2374]

that video was incredible that presentation was humongous. name of the software being used to make this video?

[@Manoj.825]

Thanks for this video's

[@slaveNo-4028]

at first i was annoyed by the style of the video, probably because many other, stupid videos have the same vibe (mainly the music in the beginnign I think). Then I realized how on point the information is and how helpful the animations are, good job!

I worked with an animator to creat this, unfortunately I don’t know what software he used.

[@yifengchen5274]

no i am more confused with all of those words, hardness, toughness, strength, is stronger material mean tougher? or more in strength, cause those go opposite ways

[@lazertroll702]

Great content, but you should put more distance between you and the microphone, consistently. It sounds like proximal effect is destroying frequency balance for most of your audio voiceover takes. The soundscape is dominated by ~100 Hz - ~400 Hz .. notching out 300 Hz by 8 db should clear up quite a bit of the existing _muddyness,_ and you may try bumping up 4 KHz a few db for sibilance legibility .. Great content, though - I had to sub! 😎

[@Lccastaldo]

Very informational. However, the music is louder than the speaker and extremely distracting. Why does there have to be repeating rhythmic music? We are forced to read the close captioning to appreciate what the narrator is saying because we are bombarded with music that is not in the background - it the main sound here.

[@hashannayanajith420]

kzbin.infog6yFmTTV43I?feature=shared Heat treatment, or heat treatment in English, is a process in which a material, usually a metal or metal alloy, is subjected to a controlled cycle of heating and cooling to change its physical and mechanical properties. This procedure is used to improve the hardness, strength, ductility, hardness, corrosion resistance and other characteristics of the material.

[@sunrevolver]

What's toughness? What kind of activity show this property?

[@sunrevolver]

@@MetallurgyData thanks!

[@markoverton5858]

Iam a little shocked that no mention of how to hold hardened rings for example that have been machined to size ready for finish grinding, avoid distortion in the hardening treatment so the final grind can be carried without distortion being a problem, I saw this process carried out in the 1950s, at Cooper split roller bearings in uk, it was 100% successful on any diameter of rings any shape or case hardened or full hardness, it was so simple heat soak quench stop quench put the item through the process with full flatness achieved, ready for grinding mostly one pass to finish size cost savings are self evident. Quench stop temp vital then air cool to room temperature hardness drops back slightly but maintains good hardness with high wear factors, section variation on materials is a consideration but can be overcome, one of the main plus here is cheaper steels can be utilised or case hardening, ?

[@sedeqalsakkf9315]

Correction:TTTD by changing the time and holding the temperature,phase can be formed.

Why is it not possible to make a metal more useful, heat treating can make it stronger, more resistant to impact, malleable, and ductile with just one process?

Heat the metal, cool it down. So simple!

[@bernardleighan3218]

Not as simple as you may think. Depending on the metal composition, you need different temperatures for hardening and tempering. Plus your cooling cycles are different for normalization, annealing, treating and tempering. The hard part is knowing the composition of your metal if it is recycled material. It seems simple, but knowledge makes a difference.

[@BariumCobaltNitrog3n]

@@bernardleighan3218 The hard part is knowing. I'll agree with that.
