Consider the hypothetical free?energy diagram of an ideal solution shown in Fig. 10.5. Now assume that a layer of pure metal A, is bonded to a layer of pure metal B, that 40 percent by weight of the couple is in the A metal layer, and that the atomic weights of metals A and B are 80 and 60 grams per mole, respectively. Furthermore, assume that the couple is held long enough at 500 K so that, as a result of diffusions, a homogeneous solid solution is obtained.
(a) What would be the free energy of the couple at the beginning of the diffusion anneal? Give the answer in Joules per mole. (b) What would be the free?energy of the homogenous solid solution at the end of the diffusion anneal? Give the answer in Joules per mole.
