[185] The role of martensite and delta ferrite on the hydrogen embrittlement of a SUS316L TIG welded joint

*Rafael Magalhaes de Melo Freire1, Shohei Uranaka1, Mitsuo Kimura1, Eita Tochigi1, Tomoya Kawabata1 (1. The University of Tokyo)

Keywords:Hydrogen embrittlement、strain-induced martensite、pre-strain at 4K、crack nucleation、SUS316L TIG welded joint

The failure of SUS316L weld metal tensile specimens in the hydrogen environment is investigated to clarify the role of delta ferrite and martensite on crack nucleation and propagation.
