Recently, the steel parts used for automobiles and trains are required to be used under higher stress than ever before in need of the weight down. To achieve this requirement of a high strength steel, it must be necessary to decrease the inclusion contents and surface defects such as decarburization, surface roughness etc.
In this study, the results of observation on the arc height, surface roughness, hardness, residual stress and fatigue life of a Al6061-T651 shot peened were obtained.
Experimental results show that the increase of arc height is tremendous by shot velocity. Also shows that increase of surface roughness, hardness and compressive residual stress, fatigue life of Al6061- T651 by shot velocity.
