Causes of Distortion during HPGQ Process of Steel Parts
Quench hardening is a necessary process for improving the mechanical and fatigue performance of load bearing steel components, but liquid quenching can lead to large distortions. High pressure gas quenching is becoming a more popular choice, with the assu

Minimizing Distortion During HPGQ Processes
Steel components, such as gears for rotorcraft transmissions, are quench hardened to improve the hardness, strength, and fatigue performance. During a quench hardening process, components are heated to form austenite, followed by quenching (either gas or

Low Pressure Carburizing Cycle Determination for High Alloy Steels
High hardenability steels with high alloy content typically contain strong carbide forming elements such as chromium and molybdenum. During carburization, alloys with high amounts of strong carbide formers may form stable carbides on or near the surface d

Modeling the Effect of Chemistry Changes on Phase Transformation Timing, Hardness, and Distortion in Carburized 8620 Gear Steel
AISI 8620 low carbon steel is widely used due to its relatively low cost and excellent case hardening properties. The nominal chemistry of AISI 8620 can have a large range, affecting the phase transformation timing and final hardness of a carburized case.
