This study systematically compares the effects of laser shock peening without coating (LSPwC) and shot peening (SP) on the microstructure and mechanical properties of near-α Ti60 alloy, addressing the knowledge gap in strain-rate-dependent deformation mechanisms and residual stress gradients.Through multi-scale characterization (EBSD, XRD, FWHM), we reveal that under 0.3 mmA intensity, SP induces the finest surface grains (32.5% of base material size) and highest compressive stress (-594.8MPa) but limited depth (~200 μm).In contrast, LSPwC at 80 mJ energy achieves deeper stress
