Question:

A Nb-60 wt% W alloy is heated to 2800 °C. Determine
(a) The composition of the solid and liquid phases in both wt% and at%;
(b) The amount of each phase in both wt% and at%; and
(c) Assuming that the density of the solid is 16.05 g/cm3 and that of the liquid is 13.91 g/cm3, determine the amount of each phase in vol%.
