A specimen of 1.5-kg of an 88wt% lead-12wt% tin alloy is heated to 220 degree Celsius temperature it is entirely an α-phase solid solution at this temperature . The alloy is to be melted to the extent that fifty percent of the specimen is liquid, the remainder being the α phase. This may be done either changing its composition while holding the temperature constant. Or by heating the alloy determinet To what temperature must the specimen be heated and how much Sn should be mixed to the 1.5-kilograms specimen at the temperature of twenty five degree celsius to achieve this state?
