Clarification of heat transfer mechanism and database construction in laser quenching

Kitagawa, Yoshihiro

Laser quenching can be locally processed in a shorter time than the conventional method. But, since the quenching depth is shallow, it is limited to some applications. The purpose of this study is to construct a database on laser quenching and to clarify the range of improvement in quenching depth based on the database. In this report, in the process of constructing the database, the internal temperature distribution and temperature transition during laser irradiation were grasped by using the temperature analysis technology, and the heat transfer mechanism during laser quenching was clarified.
