How can I get the relationship between Gibbs free energy and concentration in Sn-Ag system?

Why almost every element would be metallized in sufficiently high pressure and low temperature?

(This statement is from wikipedia, BTW). What is so special about metallic bond that is limiting high-P low-T state of a matter (as long as individual atoms exist, not white dwarf of neutron star...

Is there any study to generate solidification temperature profiles using machine learning?

We know that time dependent temperature profiles can be generated using methods like FEM which solve PDEs. Can we do same using machine learning? Has anyone come across any related study?

Try to find any paper where the system Ag-Sn has been thermodynamically modeled and you will find the functions. Just remember that G is a function of x and T and probably you will find only excess Gibbs energy in a paper (so you have to add terms connected to pure elements and terms connected to mechanical mixing).

Thank you and I have found the functions.
