Abstract: Few measurements of both internal residual stresses and distortions in quenched cylinders are found, although many individual measurements have been performed for many years since the 1920s. A water quench test of steel cylinders was carried out for evaluating length and diameter changes, as well as axial residual stress distributions in the 1940s. The effects of carbon content to quench distortions and residual stress distributions were identified from the test results. However there was no explanation of the relationship between distortions and stress distributions. Here, measurements of both stress and distortion in this test were referred to, and evaluated by, computer simulation. Simulated results verified measured distortion and stress characteristics in cylinders, and explained their relationship and generation mechanism.

Keywords: quench distortion; residual stress; heat treatment; simulation; water quenched cylinders; steel cylinders; carbon content; material properties.
