The laws of nitride phase formation are studied for the Ni-Co-Cr-W-Ti new class heat-resistant alloy, strengthened by volume nitriding. The data on kinetic features of behavior of the alloy during thermochemical treatment are obtained: the dependences of the extent of structural zones and particle size of the nitrides on the treatment time are found. A kinetic model of the volume nitriding process...
Features of the effect of alloying elements on linear thermal expansion coefficient of wrought heat-resistant alloys based on the Ni–Fe system are studied. Short-term and long-term strength at 600°C is simulated and parameters are used successfully as equivalent alloy chemical composition, calculated by a system of unpolarized ionic radii equations. A new deformable weldable alloy based on Ni–Fe–Co...
