摘要

Applying mechanical, chemical, or metallurgical treatments has become essential in modern manufacturing industries, such as railroads and automotive industries, to enhance the performance and durability of mechanical components. Among these, shot peening is widely recognized as a critical surface treatment that induces compressive residual stresses and improves fatigue resistance. This study investigates the effects of shot peening on AISI 304 stainless steel both experimentally and numerically, focusing on understanding the induced compressive residual stresses, surface hardening, and microstructural changes. The shot peening process was characterized by evaluating key parameters such as shot velocity, coverage rate, and Almen intensity. The rise in dislocation density, which aids in isotropic hardening, is the main cause of the increase in full width at half maximum, according to x-ray diffraction study. The stress distribution and deformation profiles are greatly influenced by process parameters including impact velocity and friction coefficient, as shown by numerical simulations verified by experimental results. This comprehensive approach provides valuable insights into optimizing shot peening parameters for enhanced material performance, offering a robust foundation for future industrial applications.
