Integrated Heat-Treatment Simulation with Virtual Inspection of Distorted Gears
Heat-treatment simulation is a powerful tool for gear design and process troubleshooting, but many times the predicted gear distortion is difficult to compare to physical gear measurements and to required specification charts or measurements. To help ease

Residual Stress and Bending Fatigue Strength in Carburized and Quench Hardened Pyrowear 53 Steel Gears
Carburization of alloy steels promotes the formation of compressive residual surface stress upon quenching, and that compressive surface stress enhances fatigue life. To further investigate the role of residual stress on fatigue strength, a project was un

Modeling the Effect of Carburization and Quenching on the Development of Residual Stresses and Bending Fatigue Resistance of Steel Gears
Most steel gears are carburized and quenched prior to service to obtain the desired specific strength (r/q) and hardness requirements. Use of carburization and quenching of steel gears creates a compressive residual stress on the carburized surface, which

Enhanced Surface Residual Compression of Carburized Steel Parts Using Laser Peening Process with Preload
Residual stresses are critical to the fatigue performance of parts. In general, compressive residual stress in the surface is beneficial, and residual tension is detrimental because of the effect of stress on crack initiation and propagation. Carburizatio

Bending Fatigue Strength Improvement of Carburized Gears
It is well established that carburization of low alloy steels promotes compressive residual surface stress upon quenching, and that compressive surface stresses enhance fatigue life. In an effort to build upon these established facts, a US Army sponsored
