Great video. Very informative. I however had a query: At 19:32 it is indicated that the free energy of the two phase state is lower than the single phase state of the alloy and hence, it will try to split. However, further on, while describing fluctuations, a reference is made to the free energy of phase separated state being higher to the mixed state. Can someone please explain these two concepts. Thanks
Local atomic vibration and fluctuation at nanoscale form some cluster of phase alpha 1 and alpha 2 with composition near to the alloy composition (alpha 1 rich in A element to the right side and alpha 2 to rich in B element left side) and when you join these compositions in free energy curve (within the spinodal region ) you find the tangent joining these two compositions have the lower free energy as compare to the free energy of the alloy because of which it favours this spinodal transformation of that composition (alpha 1 and alpha 2 with different composition) which keep growing over the time and spread uniformly when completed. On the other side at 19:32, the composition is outside the spinodal region which follows a totally different mode of transformation. Thanks
I wish I were your student!! You did an amazing job here, Professor.
Impressive manner to explain metallurgy. Be proud to be an excelent teacher. Greetings from Spain
I have to give a presentation on this topic next week.This has been extremely concise and interesting,provided me with the perfect guideline
Very enthusiastic professor with such a clear way of explaining thermology!
thank you ver much!!!!!! Sir Murty!!!!!!!!
from Japan as Mongolian student.
He is amazing! Lots of respect for you Professor!
Wonderful lecture! I recommend this for anyone interested in materials science issues.
Very good lecture. Helped tremendously for me to understand phase separation of liquids for my physical chemistry.
I admire your lectures and would like to have been your student if this lecture was 15-16 years ago...
omega = interaction parameter
it's used to calculate an enthalpy variation for a mixture (regular solution)
I tell you, he is amazing. Wow
Amazing explanation sir. Thank you so much
Very nice lecture. I benefit a lot.
Nicely explained. Thank you sir🙏
Great explanation

Amazing lecture. Thanking u lot.
Great teacher
very nice lecture
It was so clear!!! Thanks a lot!!
Very Nice Video :)
This is gold
Lucky to study under him. He is currently the director for IIT Hyderabad, India.
Thank you so much 😊
Beautiful !!!
Thanks sir
👍👏👏
给跪了，听不懂啊
還行吧～有字幕呀
I literally have no idea what he's saying
