Abstract
Previously, residual stresses in nitrided parts could only be measured after nitriding. This paper describes how, for the first time, residu al stress formation has been successfully monitored in-situ during the gas nitriding process, using a special nitriding device installed in an X-ray diffractometer. With this technique, the influence of nitridi ng potential, nitriding temperature, cooling process, and carbon conte nt of the investigated material can be demonstrated.
