Thermal and Transformation Stresses in Hollow Tubes during the Quenching Process,
Abstract
During the heat treatment of components, the transient thermal stresses can be very high. This is especially true if a severe quench is required such as the quenching of steel gun tubes for the development of a martensitic grain structure. In addition to the large transient thermal stresses, severe transformation stresses also exist due to the structural volume change involved. If these stresses are high enough, inelastic response of the material must be considered and residual stresses will exist in the structure when the process is complete. In this paper, both thermal and transformation stresses are computed for various quenching procedures using a hollow tube for the geometric model. The relative severity of the thermal and transformation stresses and the conditions under which they occur are discussed. A general purpose finite element code, ADINA, is used for the computation.
