Surface hardening of precipitation-hardening nonmagnetic steels
Metal Science and Heat Treatment, 19731. Precipitation-hardening nonmagnetic steels of the Fe−Mn−Ni system can be surface hardened by nitriding and also by work hardening of the surface. Surface layers with an elevated hardness to a depth of 0.3 mm can be obtained by nitriding of high-strength nonmagnetic steel 40G14N9Kh3YuF2. The results of comparative wear resistance tests showed that

Shotblasting process for surface hardening
Materials Today: Proceedings, 2021Abstract The results of studies of shot blasting as one of the methods of mechanical cleaning for surface hardening (peening) of parts are presented. The simulation in the QForm-3D (VX) software environment of high-speed impact of spherical particles on the metal was carried out and the stress–strain state of the metal in the impact hardening zone ...

Surface hardening of FCC phase high-entropy alloy system by powder-pack boriding
Surface & Coatings Technology, 2019Face centred cubic (fcc) phase high-entropy alloys (HEA) exhibit a higher ductility compared to body centred cubic (bcc) phase or multiphase HEA systems. However, low hardness and low wear resistance prevent tribological applications.
