Effect of Quenching Variables on Distortion and Residual Stresses

摘要

Using DEFORM™ finite element analysis (FEA) software, the effect of typical quenching processing variables on the hoop and radial residual stresses developed during quenching on a simple geometry (a cylinder). Process variables investigated included Racking, Quench Path, Slenderness, and Immersion Rate. Material properties evaluated include Martensite Start Temperature (M_s). The results showed that the Martensite Start Temperature (M_s) and racking were the predominate main effects in controlling residual hoop and radial stresses.
