Determine the relative amounts (in terms of volume fractions) of the phases for the alloys and temperatures given in Problems 9.10a, b, and d. The following table gives the approximate densities of the various metals at the alloy temperatures:

Metal............................Temperature (°C)........................Density (g/cm3)

Cu ...............................600........................................8.68

Mg ...............................425 .........................................68

Pb ...............................100 .......................................11.27

Pb ...............................425 .......................................10.96

Sn ...............................100 .......................................7.29

Zn ...............................600 .......................................6.67
