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 ...

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

Kinematic hardening model considering directional hardening response
International Journal of Plasticity, 2018Abstract This paper proposes a kinematic hardening model to capture both asymmetric plastic behavior (early-reyielding, transient Bauschinger effect and permanent softening) and directional hardening (anisotropic hardening) response at the same time.
