sigma-phase embrittlement

Materials science; Corrosion engineering

Embrittlement of iron-chromium alloys (most notably austenitic stainless steels) caused by precipitation at grain boundaries of the hard, brittle intermetallic sigma phase during long periods of ...

Embrittlement of low-carbon steels resulting from precipitation of solute carbon at existing dislocations and from precipitation hardening of the steel caused by differences in the solid solubility ...

885F (475C) embrittlement

Materials science; Corrosion engineering

Embrittlement of stainless steels upon extended exposure to temperatures between 400 and 510C (730 and 930F). This type of embrittlement is caused by fine, chromium-rich precipitates that segregate ...

tempered martensite embrittlement

Materials science; Corrosion engineering

Embrittlement of ultra high-strength steels caused by tempering in the temperature range of 205C to 400C (400F to 750F); also called 350C or 500F embrittlement. Tempered martensite embrittlement is ...

creep-rupture embrittlement

Materials science; Corrosion engineering

Embrittlement under creep conditions of, for example, aluminum alloys and steels that results in abnormally low rupture ductility. In aluminum alloys, iron in amounts above the solubility limit is ...

yield

Materials science; Corrosion engineering

Evidence of plastic deformation in structural materials. Also called plastic flow or creep. See also flow.

free ferrite

Materials science; Corrosion engineering

Ferrite that is formed directly from the decomposition of hypoeutectoid austenite during cooling, without the simultaneous formation of cementite. Also called proeutectoid ferrite.
