Q3) Germanium and Silicon with melting points of (958 °C) and (1430 °C) respectively form continuous solid solutions. Thermal analysis provide the following data: Alloy wt.% Si Liquidus Temp. °C Solidus Temp. °C 20 1115 990 40 1227 1050 60 1315 1126 80 1370 1230 Sketch a phase diagram using the above data and label all the important phase regions. For an alloy of (40 % Si), determine the relative amount of phases and their composition obtained on equilibrium cooling at temperature (1150 °C). Sketch a cooling curve for an alloy containing (70% Si) taking appropriate points from the phase diagram.
