Abstract:
Abstract — Induction hardening process is one kind of heat treatment process which can be used to increase the hardness on the surface of steel component. To research the effect of this method, the specimens of CT3 was used. Experience data and results were simulated and set up by 3D electro-magnetic model coupled temperature fields of COMSOL Multiphysics 5.0 software. A three-turns copper coil received the Foucault current from power supply was used for heating the specimens during experiments. The effect of process will be evaluated by measuring the hardness and metallographic techniques of material. Results showed that the martensite affect the hardness off material. The distribution of the hardness area will be depended on the result of achieved temperature located on the surface which is accordance to the shape of induction coil. In the annular zone, martensite appears almost surface areas of the annular zone, while pearlite causes the lowest hardness of the central zone.
