摘要：
Observations of fracture surfaces and deformation beneath fracture surfaces produced by hydrogen-assisted cracking in pipelines steels, which were published in a recent paper (M.L. Martin, I.M. Robertson, and P. Sofronis, Acta Materialia, 59 (2011) 3680-3687), are discussed, and it is argued that the conclusions made regarding mechanisms of fracture are not justified.
