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 ...

Subsurface corrosion

Materials science; Corrosion engineering

Formation of isolated particles of corrosion products beneath a metal surface. This results from the preferential reactions of certain alloy constituents to inward diffusion of oxygen, nitrogen, or ...

Deposit

Materials science; Corrosion engineering

Foreign substance which comes from the environment, adhering to a surface of a material.

Creep-rupture embrittlement

Materials science; Corrosion engineering

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

Quench cracking

Materials science; Corrosion engineering

Fracture of a metal during quenching from elevated temperature. Most frequently observed in hardened carbon steel, alloy steel, or tool steel parts of high hardness and low toughness. Cracks often ...

Transgranular fracture

Materials science; Corrosion engineering

Fracture through or across the crystals or grains of a metal. Also called transcrystalline fracture or intracrystalline fracture. Contrast with intergranular fracture.
