Lead and tin metals are partially miscible in the solid state. Having a melting temperature of 327C, Pb can dissolve 19% Sn in its structure at 183C. Sn, which has a melting temperature of 232C, can dissolve 2,5% Pb in its structure at 183C. The Pb-Sn duo is getimocto in eutectic mines containing 61.9% Sn at 183C. According to this a) Draw the phase diagram and show the crystallizations. b) Draw the cooling curve for the computing containing 30% Sn. C) Calculate the% by weight ratio of the alloy with composition containing 30% Sn at 300C and 200C temperatures d.) Calculate the% by weight ratio of the phases of the same composition at 183C at z1 and z2 times. (Calculate as alpha-beta.)
