n: see hydrogen embrinlement.

n: Metal becomes brittle rupture because of absorbing hydrogen.

low ductility of a metal due to its adsorption of hydrogen. More commonly called hydrogen embrittlement.

n: measure of steels ability to withstand a crack or flaw without fracturing. It can be altered by changing chemical composition, microstructure, and heat treatment. Compare brittleness.

a fatigue state of metal that may be caused by trapping atomic hydrogen in the structure of the steel. Characterized by loss of ductility. May also be caused by work hardening or other factor.

n: low ductility of a metal caused by its absorption of hydrogen gas. Also called acid brittleness.

n: opaque crystalline material, usually of high strength, that has good thermal and electrical conductivity, ductility, and reflectivity.

stress sulfide cracking. Occurs when metal is in tension and exposed to H2S and water. Generates atomic hydrogen. Hydrogen moves between grains of the metal. Reduces metal ductility.

n: measure of steels ability to withstand a crock or flaw without fracturing. It can be altered by changing chemical composition, microstructure, and heat treatment. Also called ductility. Compare brittleness.
