In many case, most of industrial materials include the residual stresses due to the manufacturing processes. The material properties, such as life length, strength of fatigue and so on, are influenced by residual stresses. The X-ray stress measurement technique is one of the effective method to estimate the residual stresses on material surface. The other hand, manufacturing processes generate the process altered layer on material surface. This process altered layer makes it difficult to measure the residual stresses by X-ray method hi material surface. Usually when the X-ray method is applied to measure the residual stresses in material surface, the process altered layer is removed by the electric polish method. In this study, quantities of electric polish which must be applied to X-ray stress measurement is investigated for aluminum alloy. The amount of suitable polish distance is defined clearly in this study.
