Computer Simulation of Residual Stress Field of Hardfacing Metal and Effect of Specimen Dimension

The distribution of the temperature and stress fields during hardfacing have been measured and simulated with steel 60CrMnMo by means of a X-ray diffraction analyzer and a software of ANSYS in this paper.The measured results show that there are two peaks of residual tension stress in the center and heat affected zone of hardfacing metal. Meanwhile,the calculated result of residual stress was compared with the measured one,which prove that the Finite Element method is effective.By using this method,the influence of different dimensions of this specimen on residual stress distribution was simulated.The calculated results show that with the increasing of the specimen dimension,the peak values of residual stress are increased and theirs positions are changed as well.
