Use the exact values you enter to make later calculations. Consider the following figure. Consider a Pb-15\% Sn alloy. During solidification, determine the following. (For each wt %Sn, if the given phase is not present, enter 0. ) (a) the composition (in wt % Sn) of the first solid to form % (b) the liquidus temperature, solidus temperature, solvus temperature, and freezing range (in C) of the alloy liquidus temperature C solidus temperature C solvus temperature C freezing range C (c) the compositions (in wt\% Sn) and amounts (as percentages) of each phase at 260C wt % Sn of liquid wt %Sn of % liquid % %% (d) the compositions (in wt\% Sn) and amounts (as percentages) of each phase at 183C wt%Snofwt%Snof%%%%%% (e) the compositions (in wt\% Sn) and amounts (as percentages) of each phase at 25C wit %Sn of % wit %Sn of % % %%
