摘要: The results of X-ray diffraction studies on Ti-48Al-1V at %(Ti-48-1) are reported. objective this study is to investigate the effects hydrogen phase changes and hydride formation in these alloys. Hydrogen-induced cracking was found occur as a result charging. appears after observed be dispersed throughout material. hexagonal formed unlike any previously reported titanium hydride. exhibits an 8% volume contraction compared Ti3Al which made up 10% a-direction, 12.5% expansion c-direction.
