Strengthening of Alloys

Strengthening of the alloys is required as metals become weak due to various lattice defects, metal bonding phenomena. The strength of the metals is not enough for any mechanical work. The internal dislocations of any metals arise due to forming processes. Due to the movement of these dislocations, the metals are plastically deformed.

Question

During heat treatment of metals, after the recovery phase, the next two stages include the following behaviours:

Internal lattice strains increase
Grains with large number of defects are formed
Grain size increases nonlinearly with time
Defect free crystal grains are formed
Total grain surface energy reduces
