Query: On the suitability of slow strain rate tensile testing for assessing
  hydrogen embrittlement susceptibility   The onset of sub-critical crack growth during slow strain rate tensile
testing (SSRT) is assessed through a combined experimental and modeling
approach. A systematic comparison of the extent of intergranular fracture and
expected hydrogen ingress suggests that hydrogen diffusion alone is
insufficient to explain the intergranular fracture depths observed after SSRT
experiments in a Ni-Cu superalloy. Simulations of these experiments using a new
phase field formulation indicate that crack initiation occurs as low as 40% of
the time to failure. The implications of such sub-critical crack growth on the
validity and interpretation of SSRT metrics are then explored.
