tensile test — a standard test piece is gripped at either end by suitable apparatus in a testing machine which slowly exerts an axial pull so that the steel is stretched until it breaks. The test provides information on proof stress, yield point, tensile… … Mechanics glossary
ultimate tensile strength — the highest load applied in breaking a tensile test piece divided by the original cross sectional area of the test piece … Mechanics glossary
compressive strength test — mechanical test measuring the maximum amount of compressive load a material can bear before fracturing. The test piece, usually in the form of a cube, prism, or cylinder, is compressed between the platens of a compression testing machine by … Universalium
Vickers hardness test — A Vickers hardness tester The Vickers hardness test was developed in 1924 by Smith and Sandland at Vickers Ltd as an alternative to the Brinell method to measure the hardness of materials.[1] The Vickers test is often easier to use than other… … Wikipedia
yield point — can be defined as the point where a tensile test piece begins to extend permanently. If the load is reduced to zero, the test piece will not return to its original length … Mechanics glossary
gauge length — used in the mechanical testing of steel, it is the length marked on the parallel portion of a tensile test piece from which the elongation is measured … Mechanics glossary
proof stress — the stress that will cause a specified small, permanent extension of a tensile test piece. Commonly the stress to produce 0.2% extension is quoted in N/mm2 for steel. This value approximates to the yield stress in materials not exhibiting a… … Mechanics glossary
materials testing — Introduction measurement of the characteristics and behaviour of such substances as metals, ceramics, or plastics under various conditions. The data thus obtained can be used in specifying the suitability of materials for various… … Universalium

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
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
