Two metals, A and B, have melting points of 400 °C and 700 °C respectively. Cooling curves were plotted for several binary alloys of A and B and the following data was obtained: % B in alloy 10 30 50 70 90 First arrest point °C Second arrest point °C Third arrest point °C 360 250 400 530 650 250 250 250 400 160 On squared paper draw accurately the equilibrium diagram for the binary alloy of A and B, and fully label this. For an alloy containing 60% B calculate: 1) The temperature at which solidification begins; 2) The ratio of phases presents at 300 °C (assuming equilibrium to have been attained).
