Investigation of the Nitride Phase in a Heat-Resistant VZh171 Alloy of the Ni–Co–Cr–W–Ti System, Hardened by Internal Nitriding
By means of the X-ray microspectral analysis and scanning and transmission electron microscopy, we investigate the composition of hardening phase particles—nitrides—after internal nitriding and subsequent heat...

Growth kinetics of particles of nitrides in process of high-temperature volume nitriding of wrought alloy of Ni-Co-Cr-W-Ti system
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 thermochemic...
