Question

a) what is the composition of alpha phase at the eutectoid composition?

b)For a 85 Wt% Pb alloy, What are the composition of first solid phase?

c)What is the composition of the last liquid remaining prior to complete solidification?

d) Is the phase Mg2Pb? (ductile, Brittle, superplastic?)

e) For a 50 Wt% Pb alloy at 481 degrees (assume eutectic temp is 480 degrees?

f) For a 50 Wt% alloy cooled to one degree Celcius below the eutectic temperature, What is the total weight fraction of a phase that is present?
