Need part a) and b) both in neat and clean handwriting. 

Two metals X and Y are mutually soluble in all proportions in the liquid state, but are completely insoluble
in each other in the solid state. Metal X has melting temperature of 280° C while metal Y melts at 320°C.

a) Draw the binary X - Y phase diagram, and label all the phase fields and the phase transformation
lines.
b) From the phase diagram you have drawn describe the phase transformations that take place when
the following two alloys are cooled from the liquid state to solid state under equilibrium conditions.
i)
An alloy containing 20% X and 80%Y.
An alloys containing 80%X and 20%Y.
