surface-hardening steel
11Diffusion hardening — Schematic cutaway view of a diffusion hardened metal gear Diffusion hardening is a process used in manufacturing that increases the hardness of steels. In diffusion hardening, diffusion occurs between a steel with a low carbon content and a… …
12Carbon steel — Iron alloy phases Ferrite (α iron, δ iron) Austenite (γ iron) Pearlite (88% ferrite, 12% cementite) …
13case-hardening — the process of hardening the surface of steel while leaving the interior unchanged. Both carbon and alloy steels are suitable for case hardening providing their carbon content is low, usually up to a maximum of 0.2%. Components subject to this… …
14induction hardening — a widely used process for the surface hardening of steel. The components are heated by means of an alternating magnetic field to a temperature within or above the transformation range followed by immediate quenching. The core of the component… …
15cyanide hardening — /ˈsaɪənaɪd ˌhadənɪŋ/ (say suyuhnuyd .hahduhning) noun the introduction of carbon and nitrogen into the surface of steel by heating it in contact with molten cyanides; a form of case hardening …
16cyanide hardening — a process of introducing carbon and nitrogen into the surface of steel by heating it to a suitable temperature in a molten bath of sodium cyanide, or a mixture of sodium and potassium cyanide, diluted with sodium carbonate and quenching in oil or …
17Work 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… …
18Precipitation 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 …
19Stainless steel — Iron alloy phases Ferrite (α iron, δ iron) Austenite (γ iron) Pearlite (88% ferrite, 12% cementite) …
20High speed steel — (often abbreviated HSS, sometimes HS) is a material usually used in the manufacture of machine tool bits and other cutters. It is often used in power saw blades and drill bits. It is superior to the older high carbon steel tools used extensively… …
