Hydrogen-Induced, Delayed, Brittle Failures of High-Strength Steels

Abstract

The Doense Me'a.3 Information Center was established at Battelle Memw!al lnstitute at the request of the Office of he Elrector of Defense)Research zrd Engineering to provide Governrnent contractors and their suppliers technical assistance and imformation on titAni,-m, beryllium, magnesium, aluminum, ref: .torymetals, high .strengthalloys for high-temperature service. corooionand exida.tion-resistant coatings, and thermal-protection systems. Its 'unctlons, under the direction of the Office of the Director of Defense. are as follows: 1. To collect, store, arid disseminate technlcal information on the cut rent status of research and developmeint of the above materials. 2. To suppltment established Service activities in providing technical advisory services to producers, melters, and fabricators of the above materials, and to designers and fabricators of military equipment containing these materials. 3. To assist. the Government agencies and their contractors in developing technical data. required for preparation of specifications for the above materials. 4. On assignment, to conduct surveys, or laboratory research investigaitions, mainly of a short-range nature, as requirzd, to ascertain causes of troubles encountered by fabricators, or to fill minor gaps iti, establishe, research programs.

Hydrogen embrittlement in irradiated steels

“…In addition to the many original papers in the literature, some of which will be referred fo below, four extensive reviews furnish valuable background information on the subject. [1][2][3][4] Hydrogen embrittlement is a quantitative phenomenon. That is, the proper combination of the various parameters results in loss of strength, and although the effect of one can be reproducibly studied by controlling certain variables, a generalized parametric picture is not available, and would probably be too complex for purposes of design or evaluation.…”
