Effect of laser-induced ultrasound treatment on material structure in laser surface treatment for selective laser melting applications

Abstract A new mechanism for controlling the microstructure of products in manufacturing processes based on selective laser melting is proposed.The usc trojans snapback hat mechanism relies on generation of high-intensity ultrasonic waves in the melt pool by complex intensity-modulated laser irradiation.The experimental study and numerical modeling suggest that this control mechanism moondrop quarks is technically feasible and can be effectively integrated into the design of modern selective laser melting machines.
