Effect of Surface Heat Transfer Coefficients on Quench Simulation Accuracy of Steel Parts

Abstract

For optimization of heat-treating process of steel parts, the improvement of the analytical accuracy in heat-treatment simulation is required. The influence of the surface heat transfer coefficients on the quench simulation accuracy was studied. It was clarified that the simulated microstructure, residual stress and distortion are very sensitive to the surface heat transfer coefficients. Therefore, we need to employ the accurate heat transfer coefficients on each surfaces of quenched steel parts.
