A review of the compatibility of structural materials with oxygen

Consideration of the problem of ignition and combustion of structural materials, particularly metals, which may come in contact with oxygen during its production, transport, and use. Following a review of the historical development of compatibility problems and research, a detailed account is given of compatibility testing methods aimed at detecting probable ignition sources, such as mechanical impact, electric sparks or flashes, heat, sound waves, abrasion, and surface fractures. A summary is presented of the ignition and combustion research reported in the literature, dwelling particularly on papers concerning oxygen-related accidents and the compatibility of metals with high-pressure oxygen. The relative oxygen compatibility of a number of common materials is discussed, including that of nickel and copper alloys, stainless steels, aluminum alloys, and titanium alloys. Finally, an effort is made to pinpoint research areas which would enhance understanding of the compatibility of bulk materials.
