Influence of Ultrasonic Nanocrystalline Surface Modification on the Microstructure and Mechanical Properties of Laser-Welded Butt Joints of AISI 304 Austenitic Stainless Steel
This study investigated the effect of Ultrasonic Nanocrystalline Surface Modification (UNSM) on the microstructure, local mechanical properties, surface condition, and tribological behavior of a laser-welded butt joint of AISI 304 austenitic stainless steel. Laser welding was performed using ER308LSi filler wire at app...
