Experimental Study On Ultrasonic Shot Peening Forming And Surface Properties Of Aaly12
, 2014 Ultrasonic shot peening (USP) on AALY12 sheet was studied. Several parameters (arc heights, surface roughness, surface topography and micro hardness) with different USP process parameters were measured. The research proposes that radius of curvature of shot peened sheet increases with time and electric current decreasing, while increases with pin ...
