Abstract:  
ABSTRACT The HCF response to shot peening of the non-ferrous alloys based on magnesium, aluminum and titanium is compared and contrasted. It is shown that magnesium alloys respond quite critically to a variation in Almen intensity. Marked enhancements in fatigue strength were observed after peening only at very low intensities. Aluminum alloys are much more tolerable with regard to Almen intensity since no overpeening effect was observed. Generally, naturally aged conditions (T4) respond to shot peening more beneficially than artificially aged conditions (T6). The response of titanium alloys to shot peening is highly dependent on the alloy class. The
