Great video! It helped me a lot in understanding the diagrams. I have a question about solid solubility. At 19:22 from the Si, Mo, Re diagram, can we say that the green point is a solid solution of MoSi2/Mo3Si2/ReSi?
The green point composition is a 3-phase mixture of MoSi2 + Mo3Si2 + ReSi. We would not say it is a "solid solution" of these three as that would imply they are soluble with each other when they are not. So a sample of this composition is inhomogeneous with regions of each of these 3 different phases; if they were soluble (a solid solution) it would be completely homogeneous in composition and structure. The relative amounts of the 3 phases that are present can be calculated from the tie-triangle.
Excellent. finally someone has taken a step and made these videos and made them really simple.
Thank you!
Excellent. I worried going in that I was too rusty on binary phase diagrams but your explanation is so clear that I didn't have any issues at all.
Glad you enjoyed it!
Hello Peter, Your videos are simply great.
Can you please arrange them in a sequence in a PlayList.
Thank you for the comment and the suggestion; I will work on creating the playlists you suggested
Really good videos for the ternary phase diagram understanding, thank you!
Happy to hear they were helpful
