High-pressure gas quenching shows ability to reduce distortion in heat-treatment

摘要

IVF - The Swedish Institute of Production Engineering Research - has recently carried out R&D in cold chamber gas quenching both of testpieces and components from industry. Rings have been quenched in gas and oil to demonstrate the degree and character of distortion in the two types of media. The distortion showed to be different which can be related to the difference in cooling characteristics. For instance, the ovality and its scatter was lower for the rings quenched in gas, see figure.
