The work aims to study the change rule of surface properties aluminum (Al) alloy after shot peening (SP), and obtain corresponding relationship between material characteristics SP parameters. Firstly, Finite Element Model (FEM) multi-projectile impact Al specimen was established by ANSYS/LS-DYNA (Version: Ansys15.0). Box-Benhnken design method (BBD) used 3-level 3-factor experiment with pressur...

Shot peening (SP) was employed to modify the surface microstructure and mechanical properties of (TiB+TiC)/Ti-6Al-4V titanium matrix composite (TMC). And evolution were characterized analyzed in detail. Transmission electron microscopy (TEM) results illustrated that nanograins introduced by effect SP hindering reinforcements deformation. The formed near reinforcement/matrix interface because sq...
