Embrittlement is a loss of ductility of a material, making it brittle. Various materials have different mechanisms of embrittlement. ==Cryogenic embrittlement== Around cryogenic temperatures plastics and rubbers become brittle, which is known as the embrittlement temperature. ...
Loss of load carrying capacity of a metal or alloy; The severe loss of ductility or toughness or both, of a material, usually a metal or alloy. Many forms of embrittlement can lead to brittle fracture. Many forms can occur during thermal treatment or elevated-temperature service (thermally induced embrittlement). Some of these forms of embrittlemen...
