Conclusions

  1. 1.

    Isothermal ordering in annealing at 550°C of hardened NiPt alloy leads to strengthening of it (σ0.2=900 MPa, σt=1200 MPa) and to a decrease in plasticity (δ≅5%).

  2. 2.

    Deformation of hardened NiPt alloy makes it possible to substantially increase its strength properties (σ0.2=1700 MPa, σt=2100 MPa). In annealing of the deformed alloy below the temperature of the phase transformation processes of stress relaxation, restoring the capacity of the material for plastic flow, and atomic ordering, increasing its resistance to deformation, occur simultaneously.
