Abstract Cold surface hardening merges the properties of specially heat-treated high-alloyed steels with structural changes induced by mechanical processes such as deep rolling. Compared to conventional transformation-induced plasticity- (TRIP-) steels these materials show noticeably better machinability because the generated austenitic structure is ...

Surface hardening of steels by plasma hardening
Metal Science and Heat Treatment, 19831. Plasma hardening of steels provides hardened layers which in hardness, thickness, and wear resistance meet the requirements for hardened surfaces of many parts of various types of machines. 2. From the results of production and testing under service conditions of lots of hydraulic motor stators and troughs of conveyers it was ...

Hardening the surface of austenitic steels by strain hardening
Metal Science and Heat Treatment, 19711. The carrying capacity in terms of permissible stress (σ0, 2) of steels Kh18N10T and Kh21N5AG7 under conditions of uniaxial static tension increases 50% down to −253° as the result of surface hardening. 2. For hardened steels Kh18N10T and Kh21N5AG7 σ b n /σn > 1 and σ b n /σ0.2 > 1 with Kt=3.0 in the range of 20 to −253° C. 3.

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

Surface hardening of case hardened steel by rolling
Metal Science and Heat Treatment, 19651. Rolling of case hardened quenched steel produces an additionally hardened layer as thick as 1 mm. At the same time, the hardness increases by 100 HV units. 2. The effect of rolling depends on the type of steel, the preliminary heat treatment, and the value of the contact stress. 3.

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 ...
