Work hardening — Work hardening, also known as strain hardening or cold working, is the strengthening of a metal by plastic deformation. This strengthening occurs because of dislocation movements within the crystal structure of the material.[1] Any material with… … Wikipedia
work hardening — increase dislocation density in metals through straining a material with an applied stress; degree of hardening may be manipulated through recovery and recrystallization … Mechanics glossary
Work aversion — Work aversion, Workplace aversion, or Employment aversion is a psychological behavior, often part of an anxiety disorder, in which the subject intentionally refuses to be gainfully employed at all, or works far less than is necessary in order to… … Wikipedia
Strain hardening exponent — The strain hardening exponent (also called strain hardening index), noted as n , is a materials constant which is used in calculations for stress strain behaviour in work hardening. In the formula σ = K ε n, σ represents the applied stress on the … Wikipedia
Induction hardening — is a form of heat treatment in which a metal part is heated by induction heating and then quenched. The quenched metal undergoes a martensitic transformation, increasing the hardness and brittleness of the part. Induction hardening is used to… … Wikipedia
Case hardening — or surface hardening is the process of hardening the surface of a metal, often a low carbon steel, by infusing elements into the material s surface, forming a thin layer of a harder alloy. Case hardening is usually done after the part in question … Wikipedia
Radiation hardening — is a method of designing and testing electronic components and systems to make them resistant to damage or malfunctions caused by ionizing radiation (particle radiation and high energy electromagnetic radiation),[1] such as would be encountered… … Wikipedia
Viscoplasticity — Figure 1. Elements used in one dimensional models of viscoplastic materials. Viscoplasticity is a theory in continuum mechanics that describes the rate dependent inelastic behavior of solids. Rate dependence in this context means that the… … Wikipedia
Strengthening mechanisms of materials — Methods have been devised to modify the yield strength, ductility, and toughness of both crystalline and amorphous materials. These strengthening mechanisms give engineers the ability to tailor the mechanical properties of materials to suit a… … Wikipedia
Peening — is the process of working a metal s surface to improve its material properties, usually by mechanical means such as hammer blows or by blasting with shot (shot peening). Peening is normally a cold work process (laser peening being a notable… … Wikipedia
