Summary

  1. 1.

    The degree of strengthening resulting from deformation in a medium of liquid hydrogen increases with increasing concentrations of Ni in the steel.

  2. 2.

    The steel with 8% Ni is the most susceptible to strengthening at the moment when the plastic flow becomes unstable.

  3. 3.

    The analysis of the variation of the extrapolated yield strength shows that the maximum possible uniform plastic deformation\((\psi _{{\text{uni}}{\text{. max}}} )\) is 15–40% for steels with 8 and 20% Ni, respectively.

  4. 4.

    Steels with 12–14% Ni are the most dependable materials for structures operated at low temperatures.
