PLEASE ANSWER QUESTION D) FOr a phomicrograph of the alloy shown
blow, please label all micro-constitents and indicate their
approximate compostions
Problem 1. For a lead-tin alloy of composition 80 wt% Sn - 20 wt% Pb at 182°C, do the following: (a) Determine the mass fractions of the a and B phases (b) Determine the mass fractions of primary (pro-eutectic) and eutectic micro-constituents. C) Determine the mass fraction of eutectic B. (d) For a photomicrograph of the alloy shown below, please label all micro-constituents and indicate their approximate compositions.
