Finer the spheroid second phase particles, better are the mechanical properties.

Finer the spheroid second phase particles, better are the mechanical properties. Correct Answer True

With the fineness, the distribution in matrix increases. Thus these particles provide more resistance to dislocation motion and retain good tensile strength. These particles also retain good ductility.
