Abstract

Results from literature show that compared to conventional quench, the intensive quench promotes better mechanical properties, reduces the dimensional distortions and cracking formation, due to high compressive tensions introduced on the component surface. To conduct the intensive quench process, high cooling rates are necessary, achieved by the use of cooling system with high severity (H>6). This project consists to compare 5160 steel samples submitted to intensive quench and convencional quenching and tempering. Residual stresses and dimensional distortion measurments will be done after heat treatment cycles.
