Strain Hardening

Also known as: Work Hardening.

An increase in hardness and strength caused by plastic deformation at temperatures lower than the recrystallization range.

This trait is particularly pronounced in soft, low-carbon steel or alloys containing nickel and manganese, nonmagnetic stainless steel, high-manganese steel and the superalloys Inconel and Monel.

Strain Hardening Exponent

Measure of increase in hardness and strength caused by plastic deformation. It is related to true stress and true strain.

See also: Modulus of Strain Hardening.
