Consider the case in which 10wt% Sn is added to Pb in order to strengthen it. The yield strength of the resulting Pb-Sn alloy is given by the equation: Oy = 150 + 25 VW + 12vT where W is the amount of B phase (in wt%) and C is the concentration of Sn in the a phase (in wt%). Calculate the yield strength of the alloy at 100°C. [Hint: Use the Pb-Sn phase diagram provided below.
