Failures of metallic components involving environmental degradation and material- selection issues
Source abstract
Abstract
Abstract Environmentally assisted failures involving poor materials selection (or heat treatment), along with some examples where the specified material was (inadvertently) not used, are described. The materials discussed are martensitic steels, stainless steels, aluminium alloys, and copper alloys. The examples discussed include some cases where the material-selection issue was with welds, coatings, or insulation rather than the component material per se. The failure modes discussed are hydrogen embrittlement, stress-corrosion cracking, corrosion fatigue, metal-induced embrittlement, galvanic corrosion, selective corrosion (dealloying), and intergranular corrosion. The characteristics of fracture/corrosion, which contribute toward correctly diagnosing the modes and causes of failure, are also outlined along with comments on the mechanisms involved.
