Abstract:  
We investigated the effect of different shot peening conditions on the fatigue strength of carburized steels. The results of investigation indicate that the shot peening is exceedingly effective in improving the fatigue strength with carburized steel specimens but its effectiveness is greatly affected by its conditions. In applying the shot peening, therefore, it is important to select the conditions that can bring out its maximum effect.
