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

Figure 8

Fracture surface investigation of Ni alloy specimen with cumulation of failure due to static loading at 293 K in hydrogen under the pressure of 30 MPa: (a) intergranular fracture in the area of surface cracks and (b) destruction along the boundary of the carbide matrix with carbide cracking.
