Abstract
Ultrasonic shot-peening was developed to densify P/M porous parts. Exp eriments were performed on a sintered Distaloy AE steel with an initia l porosity ranging from 9 to 21v/o. Quantitative image analysis was de veloped to characterize the evolution of porosity after densification. The influence of process parameters and initial porosity on the poros ity profiles was shown. The results are compared with the evolution of the surface roughness and microhardness profiles. Finally, the main p arameters were isolated.
