Influences of Shot Peening Parameters on Mechanical Properties and Fatigue Behavior of 316 L Steel: Experimental, Taguchi Method and Response Surface Methodology

Abstract Severe plastic deformation methods like shot peening (SP) are known as efficient surface treatments and grain refining processes which afford more effective properties in metallic materials. In the current research, a comprehensive study was carried out on SP of AISI 316 L steel. It included 42 different with wide range Almen intensities 12–27 A various coverage degrees (100%–1500%). Several experimental tests were conducted order to explore microstructure, size, topography, hardness, wettability, residual stresses specimens. Next, two approaches including Taguchi method (TM), response methodology (RSM) deployed for modeling, analysis, optimization. RSM TM used examine influence parameters. Based optimized results, fatigue behavior selected investigated experimentally both smooth notched Graphical abstract
