austenitic steel

Metals; Metallurgy

Steel which, because of the presence of alloying elements, such as manganese, nickel, chromium, etc. , shows stability of Austenite at normal temperatures.

austenite

Metals; Metallurgy

Phase in certain steels, characterized as a solid solution, usually of carbon or iron carbide, in the hamma form of iron. Such steels are known as austenitic. Austenite is stable only above 1333 ...

austempering

Metals; Metallurgy

Quenching a ferrous alloy from a temperature above the transformation range, in a medium having a rate of heat abstraction high enough to prevent the formation of high-temperature transformation ...

attenuation

Metals; Metallurgy

The fractional decrease of the intensity of an energy flux, including the reduction of intensity resulting from geometrical spreading, absorption, and scattering.

atomic-hydrogen weld

Metals; Metallurgy

Arc welding with heat from an arc between two tungsten or other suitable electrodes in a hydrogen atmosphere. The use of pressure and filler metal is optional.
