railway RRB JE (CBT I + CBT II) Mock Test 2024 Engineering Materials Science Structure and Properties of Engineering Materials Phase Diagrams
The binary phase diagram of metals P and Q is shown in the figure. An alloy X containing 60% P and 40% Q (by weight) is cooled from liquid to solid state. The fractions of solid and liquid (in weight percent) at 1250°C, respectively, will be
1
77.8% and 22.2%
2
22.2% and 77.8%
3
68.0% and 32.0%
4
32.0% and 68.0%
