Interpretation:
Whether A-10% B alloy is a good option for age hardening or not needs to be determined. If it is a good option, the required heat treatments with appropriate tempertures need to be explained.
Concept introduction:
Phase is defined as the homogeneous portion of the system having same physical and chemical characteristics.
A diagram which defines the existence of different phases of a system under equilibrium is known as phase diagram. It gives the relationship between composition and temperature.
The phase diagram is shown in figure,
