Abstract In order to analyze the fatigue property and residual stress relaxation process of microshot peened medium carbon steel, the 109 cyc fatigue tests of the specimens unpeened and shot peened by steel balls and ceramics balls with 100 $\mu$m in diameter were carried out by rotary bending fatigue machine in air at room temperature. The result shows that the fatigue limits of specimens peened by steel balls and ceramics balls are improved by 35% and 23% respectively, compared with that of unpeened specimen. Based on the test result of the residual stress in the fatigue process, the process and mechanism of residual stress relaxation are analyzed in detail. The cyclic yield strength of the material is the main factor controled the improvement level of the fatigue limit.
