Silver copper phase diagram

Below is a Phase diagram for silver and copper. It has a lot more going on in it than the gold silver one we were looking at before. Silver and copper are not 100% mutually soluble; they actually form a duplex alloy where there are two separate crystal structures formed by alloying silver and copper.

A phase diagrams show what phases exist at equilibrium and what phase transformations we can expect when we change one of the parameters of the system. Real materials are almost always mixtures of different elements rather than pure substances: in addition to T and ... Copper - Silver phase diagram liquid

Peritectic points are spots on the phase diagram at which, upon heating, a one phase solid transforms into a different solid phase mixed with a liquid. On this diagram, the peritectic is at about 38 at% platinum and 1188°C. At this point, the pure silver phase, upon heating, will decompose into a liquid mixed with the pure platinum phase.
