Determine The Relative Amounts In Terms Of Volume Fractions Of

Determine the relative amounts (in terms of volume fractions) of the phases for the alloys and temperatures given in Problem 9.8a, b, and c. Below are given the approximate densities of the various metals at the alloy temperatures:
(a) 90 wt% Zn-10 wt% Cu at 400(C (750(F)
(b) 75 wt% Sn-25 wt% Pb at 175(C (345(F)
(c) 55 wt% Ag-45 wt% Cu at 900(C(1650(F)
