NEW CONTRIBUTION TO MECHANISMS OF HYDROGEN-INDUCED CRACKING AND STRESS-CORROSION CRACKING

摘要

＜正＞ Ⅰ.MECHANISM OF HYDROGEN-INDUCED CRACKINGIn some cases,hydrogen is a useful element.For example,hydrogen may enhance theself-diffusion of titanium,stabilize the more hot-workable β phase and then improve the hotworkability of titanium alloys;hydrogen as a temporary alloying element could change the
