Notes:
Recently, the steel parts used at the aerospace and automobile industries are required to beused high stress more than ever before in need of the weight down. Therefore, used material steel haveto be a high stress, which is an indispensable condition in this field. At the consideration of partsdesign, high hardness of the lightweight parts has an benefit of saving fuel and material. In this study,the surface conditions are measured to know the influence on fatigue properties by shot peening. Inthis study, the optimum shot peening condition is investigated. Fatigue test was accomplished toinvestigate the effects of compressive residual stress by shot peening on fatigue characteristics. Testresults show the fatigue characteristics were increased by optimum peening condition. But the fatiguecharacteristics were decreased by under peening or over peening condition
