In-situ Improvement of Work Hardened Area of Stainless Steel by Solution Treatment using YAG Laser

Abstract

We have developed a in-situ heat treatment system using YAG laser on the machine tools table. In the Present report, we applied this system to a solution treatment of the work hardened area of the stainless steel. We carried out the experiments of laser irradiating the work hardened stainless steels under various conditions. As a result, it is confirmed that the solution treatment can be done by proper laser irradiation conditions on the machine tools table.
