a. Do the Hume-Rothery rules suggest this type of solid solution behavior, and discuss why or why not.
b. At 1000oC, what phases would be present and what would their compositions be for a 30 at% Ni composition, for a 50 at% Ni composition, and for an 80 at% Ni composition.
c. At 1000oC, how much of each phase present would be found for a 30 at% Ni, composition, for a 50 at% Ni composition, and for a 80 at% Ni composition.
d. If you were to heat a 30 at% Ni, composition, a 50 at% Ni composition, and an 80 at% Ni composition from 600oC, at what temperature would the first liquid form for each composition?
