I listened to my professor lecture about TTT diagrams for 4 hours and didn't understand any of it until now. This 6 minute video connected all the dots so beautifully. Well done sir!
This DVD is supremely helpful and I have watched it 12 times in the last six months. Every time I watch it I pick up something new. And yes I just watched this whole video again
I definitely gotta pick up your dvd sometime. I've studied/learned and re-studied/relearned many of these terms and what going on with the atoms over the years but just I don't practice using them enough for them to remain in my memory, not to mention never being 100% clear on certain matters. But with your visuals and super simple way of presenting these things, not to mention your passion, will surely help with that. Btw, the video and editing look great. Thanks for sharing!
I greatly enjoyed this dvd and am greatly looking forward to your future dvds. I think I saw your post on fb on what's coming next but not 100% sure, so would it be alright to ask what steel is going to be on the next dvd? ...and that one after that maybe?
I am currently in the process of doing the lab work for a 52100 DVD/video, but it is the opposite end of the spectrum from 1084. 1084 was about the easiest steel to work with and study, 52100 is one of the more complicated (among simple steels) and my research is taking much longer.
Sir we've already seen that for an alloy, transformation occur at a range of temp.(except for eutectic composition)...but in TTT diagram phase transformation start and finished at the same temp...HOW IS THIS POSSIBLE?? plz help🙏🙏
If I understand your question correctly I think the answer to your question may be in the difference between the TTT (I-T) diagram and the Continuous Cooling diagram. The TTT is isothermal in that is reflects the transformation when the alloy is cooled to a given temperature and held there until transformation is complete. Thus the hold reflects eventual equilibrium conditions. The Continuous Cooling curve more accurately reflects what happens when there is no hold and shows the resulting phases from cooling continuously at different rates. At the other end of this spectrum would be the Fe-Fe3C equilibrium diagram which only accounts for phases at static temperatures with no reflection of time.
I wish my lecturers had as much enthusiasm as this guy! Loved the explanation.

That is very rewarding to hear, thank you, I am glad it helped.

hey I think you need to do more of this! Your way of explaining is super clear, you did a great job!
Thank you Kevin for putting this video up. Over the few years I've been playing with knifemaking I've learned so much from you. THANK YOU!!! Ken H>
That was cool. Thanks for making the time to put this info up.
yeah, pretty cool...it probably avoided quite well the formation of perlite...
All the informations are so clearly explained !
Looking forward to purchasing this DVD.

This is a great explanation. Thank you
You're very welcome!
Really cool ..Kevin and Thanks indeed
Simply put!
Superb
So good
informative and funny
Simple as that, thanks a lot

@@kevinr.cashen8544 I look forward to it
Kevin, have you guys done any research for how bloomery mass can be made that has very low Phos annd sulfer, and how do you get manganesse in
