Laser Quenching and Forming Method for Thin Steel Plate under Preheating Conditions

抄録

The focus of this study was high efficiency laser quenching and laser forming, which are simultaneously achieved by the laser quenching-forming method proposed in this paper. Laser quenching-forming is premised on laser scanning repeatedly. Therefore, it is necessary to consider the influence of heat accumulation by repeated laser scanning. The deformation angle when the workpiece was preheated was investigated. Quenching was evaluated for quenching from the viewpoint of hardening range, hardening hardness, cooling rate. Accordingly, deformation and quenching behavior using preheating conditions were determined. It has been shown that laser quenching forming is possible even by repeated laser scanning.
