Summary

The work described in this paper is a study of the effect of a range of process parameters on the residual stress profiles produced by shot peening coupons of case carburized 17CrNiMo6 steel.

The peening process utilized for the research was undertaken using a commercial shot-peening unit supplied by USF Vacu-Blast Limited using 0.6 mm diameter shot. The process parameters investigated included air pressure, the mass flow, the impact angle, the distance between the nozzle and the specimen, the exposure time and the nozzle size. Using Minitab v12 software regression analyses were performed on the results obtained from the statistically designed experiments. It was found that the most significant parameters were air pressure, the mass flow, the impact angle and the exposure time. Further important and significant interactions were also detected between exposure time and air pressure; nozzle size and mass flow; air pressure and impact angle; nozzle size and air pressure.
