Its the same; you conserve mass rather than atoms. So the derivation is exactly the same.

If you are in a two phase region, read across T to the phase boundaries. In a single phase region, then its the alloy composition.

What about calculating the phase fractions for eutectic systems. I am guessing the vs + vl will not be 1, and the best way i can describe it is that vs and vl will turn out opposite...

Thank you very much for this perfect explination! I have a question though. When is asked: Give me the (T,t) diagram => Temperature,time using ''De fasenregel van Gibbs" (IDK in English, fase-rule of Gibbs perhaps...). How does the diagramlooks like then? During the 2fase part (melt+solid) I have: (Gibbs) V=1+2-2=1 So the temperature can variate. Is this correct? And during the 1-fase parts I have: V=1+2-1=2 ?? What does that mean? 2 Parameters that can variate... but which ones? Thanks

This could be a very nice explanation. The only problem with it is that it is not true! It is true for mass fractions / weight fractions BUT since the densities of solid & liquid are different (in general), the rule can't be applied to volume fractions...
@DavidDyeIC

You are correct, of course. That's why I am flaky as to whether I am calculating a volume, area, weight or mole (atom) fraction of phase - this point is made in the notes. In practice in metallurgy, we measure the area fraction using microscopy, very commonly. And we assume that this corresponds to the volume fraction and to the weight fraction we calculated using the phase diagram (which is usually in wt.%). This is the custom in the subject; don't let it worry you.

Yes, the formula is obviously rigorously untrue when used for volume fractions, but he seems to suggest in the video that he uses this quite often, leading me to believe that perhaps the error due to the difference in densities is quite small for common materials?
