Behavior of a Complex Steel Part During Hardening Heat Treatment Free

Heat treatment response of a complex shaped cylindrical component with varying sections of thickness and length has been studied in a 15CDV6 bainitic steel. The effect of cooling rate at every location has been predicted using an FEM based simulation. The distortion associated with the experimental component was matched with the theoretical FEM based heat treatment model. The component distortion has been attributed to the strain associated with volume changes associated with thermal gradient and phase transformation at various locations. The heat flux on the surface was modelled to arrive at heat transfer by inverse technique. The study validates the definition of boundary conditions for such complex components.
