Abstract

Measurements of quench distortion and internal residual stresses in quenched cylinders have been performed for many years. Distortion and stress distribution patterns have been identified in the typical steels and cooling conditions. Pioneers of the heat treatment simulation compared their simulated results with experimental data obtained and reported in the 1970s and 1980s. However, these early researchers did not fully explain the mechanism of distortion and residual stress generation based on their simulated results. Although there were several reports on distribution changes of stress, similar reports relating to strains were rarely reported. In this research, water quenched steel cylinders were simulated and an origin of distortion and residual stress generations was explained using the simulated stress and strain distribution changes.
