Hydrogen Effect on Cumulation of Failure, Mechanical Properties, and Fracture Toughness of Ni-Cr Alloys

Figure 2

Dependences of fracture toughness K_c of prehydrogenated (623 K, 30 MPa H₂, 10 h) specimens of 20 mm thickness on the hydrogen pressure at a strain rate of 0.1 mm/min. The numbers near curves correspond to ordinal numbers in Table 2.
