THE EFFECTS OF HARDENING DEPTH AND TEMPERING TEMPERATURE ON RESIDUAL STRESS DISTRIBUTION IN MEDIUM FREQUENCY INDUCTION HARDENED RAILWAY CAR-AXLES

To develop optimum induction hardening conditions for improvement of fatigue strength of axles, the effect of hardening depth and tempering temperature on residual stress distribution in specimen steel axles was investigated. Residual compressive stress in the surface and residual tensile stress in the center were produced by medium frequency hardening. Medium frequency induction hardening and 200 C tempering may be optimum for axles from the viewpoint of residual stress distribution and toughness of the hardened case.
