The influence of grain size on the hydrogen embrittlement of titanium sheets is shown to depend on stress state. Results are presented which indicate that the deleterious effect of a large grain size on the susceptibility to hydrogen embrittlement is more severe in equibiaxial tension than in uniaxial tension. This effect may be understood in terms of the sensitivity of both void nucleation due to hydride fracture and void link-up due to the combined effects of large grainhydride fracture and void link-up due to the combined effects of large gainhydride sizes and the large multidirectional, normal stresses that develop during deformation of plastically anisotropic sheets in equibiaxial tension.
