Residual Stress and Fatigue Strength of Carburized Steels and Gears 2002-01-1559
The residual stress of carburized and hardened gears have profound influence on durability. Residual stress of carburized and quenched steel varies with steel hardenability, carburizing processes, quench methods and case depth. The residual stress of carburized steels is further increased by post peening operations which improves the durability of case hardened components.
This paper summarizes the influence of case depth, core hardness and the post peening process for future gear design.
