What are the differences between the solidification of pure metals and metal alloys?
Solution
During solidification, pure metal converts from liquid state to solid sate at a single temperature
while an alloy solidifies over a range of temperature. Pure metal composition remains constant
throughout solidification process but the composition of alloy changes continuously. But the
composition of alloy in the solid sate becomes same as that when it was in liquid state.that is, this
change of composition take place only during liquid+ solid state. Importantly , all this occurs
only during cooling under equilibrium conditions..
