strain-hardening material
41Cryorolling — is one of the potential techniques to produce nanostructured bulk materials from its bulk counterpart at cryogenic temperatures. It can be defined as rolling that is carried out at cryogenic temperatures. Nanostructured materials are produced… …
42Dual-phase steel — (DPS) is a high strength steel that has a ferrite and martensitic microstructure. DPA starts as a low or medium carbon steel and is quenched from a temperature above A1 but below A3 on a continuous cooling transformation diagram. This results in… …
43Blow molding — The blow molding process Blow molding (also known as blow moulding or blow forming) is a manufacturing process by which hollow plastic parts are formed. In general, there are three main types of blow molding: extrusion blow molding, injection… …
44Al-Li — alloys are a series of alloys of aluminium and lithium, often also including copper and zirconium. Since lithium is the least dense elemental metal, these alloys are significantly less dense than aluminium. Commercial Al Li alloys contain up to 2 …
45Meyer hardness test — This graph shows the differences between the Brinell hardness test and the Meyer hardness test. Notice that the Brinell test can report the same hardness value for a given specimen twice depending on the load. The Meyer hardness test is a rarely… …
46Autofrettage — is a metal fabrication technique in which a pressure vessel is subjected to enormous pressure, causing internal portions of the part to yield and resulting in internal compressive residual stresses. The goal of autofrettage is to increase… …
47Alan Needleman — was born in 1944 in Philadelphia, PA and is currently the Florence Pirce Grant University Professor of Mechanics of Solids and Structures at Brown University in Providence, RI. Professor Needleman received his B.S. from the University of… …
48Strength of materials — Internal force lines are denser near the hole, a common stress concentration In materials science, the strength of a material is its ability to withstand an applied stress without failure. The applied stress may be tensile, compressive, or shear …
49Hardness — This article is about mechanical properties of materials. For other uses, see Hard. Hardness is the measure of how resistant solid matter is to various kinds of permanent shape change when a force is applied. Macroscopic hardness is generally… …
50Necking (engineering) — A polyethylene sample with a stable neck. Necking, in engineering or materials science, is a mode of tensile deformation where relatively large amounts of strain localize disproportionately in a small region of the material.[1] The resulting… …
