Any of several plastic deformations of metal (or other material) at relatively low temperatures
Plastic deformation performed on a material, usually at room temperature, so as to increase its yield strength and tensile strength (See "strain hardening ")
Plastic deformation at such temperatures and rates that substantial increases occur in the strength and hardness of the metal visible structural changes include changes in grain shape and, in some instances, mechanical twinning or banding
the rolling or bending of material at ordinary room temperature or of steel under concentrated forces
Deforming metal plastically at a temperature lower than the recrystallization temperature Mechanical or hydraulic expansion employed to achieve higher mechanical properties
Low-risk work in a nonrestricted area (outside a 50 meter radius of a live surface facility) Eg: grading a road
Plastic deformation of metal at such temperature and rate that substantial increases occur in strength and hardness
