Research Abstract

In the present study, characterization and mechanism of hydrogen embrittlement accompanied with phase transformation have been elucidated by considering interaction between dynamic process of phase transformation and hydrogen. The several results can be applied to elucidate the hydrogen embrittlement of practical alloys without phase transformation. In addition, the present findings will become the basic guide for the materials development and the improvement of materials reliability.
