Unformatted text preview: phases are solid solutions? (b) For any given point in the phase diagram (T,x) you can obtain three pieces of information: the phases present, the compositions of all phases present and the fractions of all phases present. How? (c) Given the phase diagram that you drew, what is the maximum solubility of B in A at onehalf the eutectic temperature? Assuming your diagram is drawn correctly, what is the maximum solubility of B in A in the limit T → 0? Problem 4: (a) The principal contribution to the specific heat of a metal comes from the lattice vibrations. The valence electrons are, ordinarily, much less important. Why? (b) The entropy of a solid solution of A and B is always higher than the entropy of an ordered compound of the same elements. Why? Engineering 45: Midterm Exams 19872005 Page 29 (c) While valence electrons do not contribute much to the specific heat of a metal, they are the primary source of its thermal conductivity....
