Abstract

The effect of shot peening on surface integrity was described. After shot peening was performed tor carbon steel under several conditions with steel shot, peened materials were heat-treated at various temperatures and times (100-600°C, 15-240 min), and then hardness, half width and surface residual stress were measured. The following results are obtained: (1) non-affected layer induces compressive residual stresses on the peened surface and surface layer, (2) hardness increases after heating at 200-400°C, but decreases in case of 600°C, (3) compressive residual stresses decrease after all heat treatments, (4) microstructure may be recovered by heat treatment at low temperature.
