    Strengthening is the method to improve the strength of material because different type of material property requires for different requirement. Some times requires more ductility, some time requires more strength.

    When impurities are mixed with the pure metal then the strength of metal will increases and this is called the strengthening of metal.

    The methods of strengthening are as follows

    1. Solid solution strengthening and alloying

    2. Work hardening

    3. Transformation hardening

    4. Grain boundary strengthening

    5. Precipitation hardening
