Stress–strain curve — During testing of a material sample, the stress–strain curve is a graphical representation of the relationship between stress, derived from measuring the load applied on the sample, and strain, derived from measuring the deformation of the sample … Wikipedia
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
Precipitation hardening — Precipitation hardening, also called age hardening, is a heat treatment technique used to increase the yield strength of malleable materials, including most structural alloys of aluminium, magnesium, nickel and titanium, and some stainless steels … 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
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
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
surface hardening — ▪ metallurgy treatment of steel by heat or mechanical means to increase the hardness of the outer surface while the core remains relatively soft. The combination of a hard surface and a soft interior is greatly valued in modern engineering… … Universalium
Flow stress — is defined as the instantaneous value of stress required to continue deforming the material to keep the metal flowing. It is the Yield Strength of the metal as a function of strain, which can be expressed: [1] Yf = Ke^nYf = Flow stress, MPaK =… … 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
Parallels (engineering) — Engineering parallels are rectangular blocks of metal, commonly tool steel, stainless steel or cast iron, which have 4 or 6 faces ground or lapped to a precise surface finish. They are used when machining with a miller, drill or any other… … Wikipedia
