Modeling on stress evolution of step part for casting-heat treatment processes

摘要：

Heat treatment usually follows the casting process to improve the physical properties of parts. Under the strong assumption that casting has no effect on the following heat treatment, the modeling of heat treatment process is currently based on ideal material conditions with zero residual stress and uniform properties. In this paper, residual stress generated by casting has been introduced as the initial conditions for a heat treated step part of 4140 steel. The results have been compared with that of no consideration about initial residual stresses of casting.
