Is it possible to have a copper-silver alloy of composition 20 wt% Ag- 80% Cu that, at equilibrium, consists of LaTeX: \alphaα and liquid phases having mass fractions WLaTeX: \alphaα = 0.80 and WL= 0.20? If so, what will be the approximate temperature of the alloy? If such an alloy is not possible, explain why.

Answer:

800°C

Explanation:

Phase diagram of an alloy is a graphical presentation showing the phases compositions and their relative amounts at any different temperature and under equilibrium conditions. It is used to predict the phase changes of the alloys at different temperatures.

From the figure, we can see that the tie lines are proportional about α + L at a temperature of 800°C for [tex]W_\alpha =0.8[/tex]
