martensite — a metastable iron phase supersaturated in carbon that is the product of a diffusionless (athermal) transformation from austenite. Very rapid cooling (quenching) of steel (at about 1,000(C per minute) produces a new microstructure, martensite. It… … Mechanics glossary
secondary hardness — an increase in hardness which sometimes occurs when hardened steel is re heated. It can be caused by the transformation of retained austenite to martensite or by the precipitation of alloy carbides … Mechanics glossary
metallurgy — metallurgic, metallurgical, adj. metallurgically, adv. metallurgist /met l err jist/ or, esp. Brit., /meuh tal euhr jist/, n. /met l err jee/ or, esp. Brit., /meuh tal euhr jee/, n. 1. the technique or science of working or heating metals so as… … Universalium
steel — steellike, adj. /steel/, n. 1. any of various modified forms of iron, artificially produced, having a carbon content less than that of pig iron and more than that of wrought iron, and having qualities of hardness, elasticity, and strength varying … Universalium

Maraging steel — Maraging steels (a portmanteau of martensitic and aging ) are steels (iron alloys) which are known for possessing superior strength and toughness without losing malleability, although they cannot hold a good cutting edge. Aging refers to the… … Wikipedia
Katana construction — was the labour intensive bladesmithing process developed in Japan for forging katana and other Japanese blades. Katana and wakizashi were often forged with different profiles, different blade thicknesses, and varying amounts of grind. Wakizashi… … Wikipedia
Tempering — For other uses, see Temper (disambiguation). Tempered steel. The various colors produced indicate the temperature to which the steel was heated. Light straw indicates 204 °C (399 °F) and light blue indicates 337 °C (639 °F) … Wikipedia
Diffusionless transformations — are a class of phase changes that do not occur by the long range diffusion of atoms but rather by some form of cooperative, homogeneous movement of many atoms that results in a change in crystal structure. These movements are small, usually less… … Wikipedia
