A metal finishing machine is a specialized piece of equipment utilized to enhance the durability and performance of metal components. The process involves bombarding the surface of the component with small, hard projectiles, typically made of steel or glass beads. This forceful impact creates compressive residual stresses on the surface of the mate

Fatigue life of metallic components is a critical factor in numerous applications, influencing their durability. WPC treatment emerges as a promising technique for enhancing fatigue resistance. This comprehensive analysis delves into the mechanisms underlying WPC's effectiveness, examining its influence on microstructure and residual stress distrib
