Question:
A 1.5-kg specimen of a 90 wt% Pb???10 wt% Sn alloy is heated to 250oC (480oF); at this temperature it is entirely an a-phase solid solution (Figure). The alloy is to be melted to the extent that 50% of the specimen is liquid, the remainder being the a phase. This may be accomplished either by heating the alloy or changing its composition while holding the temperature constant.
(a)?? ? ??To what temperature must the specimen be heated?
(b)?? ? ??How much tin must be added to the 1.5-kg specimen at 250?C to achieve this state?
