Question

Using the phase diagram below,  for an alloy with the composition  30 wt% Pb-70 wt% Mg at 200 ° C,  determine the phases present and the phase compositions (in wt% Pb)

Accepted Answer

the  α  and Mg 2 Pb phases are present; the composition of  α  is 5 wt% Pb, the composition of Mg 2 Pb is 81 wt% Pb

Answer

only the  α  phase is present; its composition is 30 wt% Pb-70 wt% Mg

Answer

only Mg 2 Pb is present, the composition is 30 wt% Pb-70 wt% Mg

Answer

the  α  and Mg 2 Pb phases are present; the composition is the same

Answer

the  α  and Mg 2 Pb phases are present; the composition is 30 wt% Pb-70 wt% Mg
