Figure 3. Superior tensile properties and deformation microstructures of hydrogen charged 97(CoCrNi)-3Mo samples. (A) Engineering stress-strain curves of Mo-doped and undoped CoCrNi alloys with and without hydrogen. (B and C) Microstructures of hydrogen-charged 97(CoCrNi)-3Mo alloy near the fracture surface showing high-density NTs. Note that hydrogen charging was performed in a 100 MPa hydrogen gas environment at 200 °C for a duration of 160 h (Reproduced with permission^[55]. Copyright 2021, Elsevier). NTs: Nanotwins.
