The followings are the bulk property of two metals: metal A and metal B:
Metal A: The melting temperature is 1,000 K with a fusion of 10,000 J/mole.
The cP for solid phase is (21 + 5*10-3 * T) J/moleK.
The cP for liquid phase is 31 J/moleK.
Metal B: The melting temperature is 1,200 K with a fusion of 12,000 J/mole.
The cP for solid phase is 20 + 6*10-3 * T J/moleK.
The cP for liquid phase is 40 J/moleK.
Assuming metal A and metal B form ideal liquid solution and regular solid solution (GXS =
3000R XAXB, where R, XA, and XB are gas constant, mole fraction of metal A and mole
fraction of metal B, respectively), respectively, please draw the phase diagram for this binary
system.
In the calculation, you may assume that the cp for both liquid and solid phase can be
employed at any temperature.
