摘要

In this investigation, analysis of surface topography on Duplex Stainless Steel (DSS) AISI 2205 was carried out under the shot peened and various machined conditions. The surface profiles of the shot peened, polished, milled, ground and as received conditions were compared in micron level. In order to study the influence of shot peening on the profile of surface roughness, DSS samples were peened using S390 shots for different durations. Severe Plastic Deformation (SPD) was observed on the surface of DSS due to peening. Also, peening has more effect on the austenite phases than the ferrite phases on DSS surface. The shot peened surface profiles obtained using S390 shots offer better topography as compared with the other machined and as received surface conditions. As a part of the study, the effect of dual shot peening was inspected by peening the surface using two shots which introduce lots of micro peaks and valleys on the surface of DSS.
