How is the concept of diagram(b) different from that of (e) and (d) from (f)?Someone told me in one of my earlier posts (Why will A atoms diffuse from β phase to α phase and B atoms from α phase to β phase?) that he is used to see graphs with two minimia but somewhere where we had two phase separately named as $G^{\alpha}$ and $G^{\beta}$ vs the composition curve he seemed something that he saw for the very first time. Please help me to differentiate the two of them and also answer the question that I have in this post.

  • $\begingroup$ (a)(b) is normal diffusion producing one phase of A and B mixed (c)(d) is phase separation. Look at the way the arrows point. $\endgroup$ – porphyrin Jul 20 '19 at 16:35
  • $\begingroup$ @porphyrin How are we so sure that this is not a single phase?And how did u conclude the fact of diffusion and phase separation. $\endgroup$ – user586228 Jul 20 '19 at 17:01

  • $\begingroup$ @JonCuster Are you saying that (d) and (f) is the same thing? $\endgroup$ – user586228 Jul 20 '19 at 18:35
  • $\begingroup$ I have no idea what they are trying to represent in (f). But, the stable configuration would be similar for (d) and (f), yes. $\endgroup$ – Jon Custer Jul 20 '19 at 19:06
