The lever rule - DoITPoMS The proportions of the phases present are determined by the weights needed to balance the system. So, fraction of phase 1 = (C 2 - C) / (C 2 - C 1) and, fraction of phase 2 = (C - C 1 ) / (C 2 - C 1 ).

Thus, the area fraction of primary α is 104/644 = 0.16, which is also assumed to be the volume fraction. We now want to convert the volume fractions into mass fractions in order to employ the lever rule to the Pb-Sn phase diagram.
