A 45 wt% Pb-55 wt% Mg alloy is rapidly quenched to room temperature from an elevated temperature in such a way that the high- temperature microstructure is preserved. This microstructure is found to consist of the a phase and M82PB, having respective mass fractions of 0.65 and 0.35. Determine the approximate temperature from which the alloy was quenched. Use Animated Figure. °C
