Consider a 55 wt% Sn–45 wt% Pb alloy at 160˚C,
a. Cite the phases present
b. Calculate the relative amount of each phase present in terms
of (a) mass fraction and (b) volume fraction.
Note: Locate the required points clearly on Lead-Tin phase diagram. Take
necessary values wherever required and mention the reference against
every value you take, e.g. any online source/book or research paper
mass fractions of α and liquid phases are both 0.5 for a 50 wt% Sn-45 wt% Pb alloy
The volume fraction of phase α,
