Solution

Solution 1

What is the melting point of pure copper 1980 F

Solution 2

For Cu-Ag containing 30 wt % Ag

a)What phase are present at 780 C ? Solid and Liquid

b) What is the composition of each phase . Solid, Liquid

C) What is the mass fraction of each phase

W= (71.9-30)/(71.9-8) =0.655*100=65.57%

Wl= 100-65.57 =34.43%

Solution 3

What is the solibility limit in wt% Ag of Ag in Cu at 700 C 5%

Solution 4

What is the solubility limit, in wt % Ag of Ag in liquid at 900 C 8%
