Residual stress field of carburized specimens was determined experimentally and simulated by using a finite element method (FEM). The experimental results show that the compressive residual stress is formed in carburized layer of the specimen. The peak value of compressive stress appears inside of carburized layer. The calculated results are tallied with the measured ones quite well, which proves the FEM model used for simulation is correct. According to this model, the stress field of carburized specimen during quenching process was also analyzed in this paper.
