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.
