Development of Laser Heat Treatment Process for Assisted Forming of Aluminum Alloys

Abstract

This study presents information regarding the development of a localized laser-induced heat treatment for aluminum alloys. Such a process is intended to improve the forming behavior of aluminum parts in challenging metal-forming conditions. This study details information on material, heat treatment parameters as well as results for strength, hardness, and elongation properties. It was concluded that it is possible to locally modify yield strength and hardness using laser control parameters and process duration suitable for industrial applications.
