(a)
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,
Phase diagram represents the relation between composition of components in weight percent and temperature.
