Journal ArticleDOI
Embrittlement of a ferrous alloy in a partially dissociated hydrogen environment
TL;DR: Quenched and tempered steel, investigating embrittlement as function of temperature in partially dissociated atomic hydrogen environment as mentioned in this paper, was used to investigate the effect of temperature on steel embrittlements.
Journal ArticleDOI
Environmental hydrogen embrittlement of an α-β titanium alloy: Effect of microstructure
TL;DR: In this paper, the authors studied the environmental hydrogen embrittlement of a Ti-6 Al-4 alloy as a function of test displacement rate and variations in alpha-beta microstructure.
Journal ArticleDOI
Gaseous hydrogen-induced cracking of Ti-5Al-2.5Sn
TL;DR: In this article, the relationship between hydrogen-induced crack growth rate and applied stress intensity can be described by three separable regions of behavior: high stress intensity, low stress intensity and intermediate stress intensity.
Journal ArticleDOI
A film-rupture model of hydrogen-induced, slow crack growth in acicular alpha-beta titanium
TL;DR: In this paper, a study has been conducted of the terrace-like fracture morphology of gaseous hydrogen-induced crack growth in acicular alpha-beta titanium alloys in terms of specimen configuration, magnitude of applied stress intensity, test temperature, and hydrogen pressure.
Journal ArticleDOI
Phase relations in the Fe-Ni-Cr-S system and the sulfidation of an austenitic stainless steel
TL;DR: In this article, the stability fields of various sulfide phases that form on Fe-Cr, Fe-Ni, Ni-Cr and Fe-cr-Ni alloys have been developed as a function of temperature and the partial pressure of sulfur.
