Abstract
It is crucial to understand the hydrogen embrittlement behavior when steels become high strength, since hydrogen which invaded the materials often reduces their strength and ductility. The phenomenon that materials under the static load fail after a certain period of time is called delayed fracture, which has been also considered to be caused by hydrogen. The influence of hydrogen on the mechanical property of high-strength austenititic steels has been investigated, and it has been reported that hydrogen sometimes does not cause brittle fracture. In the present study, the slow strain rate technique is made to investigate the hydrogen embrittlement behavior in cold-rolled high-strength Fe-Ni-Al-C alloy specimens.
