1前言采用X射线测量应力一般是评定材料表面的应力。实际是，使用特性X射线穿透深度的累计平均值。因此，测量由压延和磨削加工等而产生表面应力斜率的材料剩余应力分布时，用过去的sin2Φ中法正确评定是困难的。所以，为评定这类的应力分布提出多种新的测量方法。在本研究中示 1 Introduction The use of X-ray measurement of stress is generally to assess the surface of the material stress. Actually, the cumulative average of the characteristic X-ray penetration depths is used. Therefore, when measuring the residual stress distribution of the material resulting from the slope of the surface stress due to calendering and grinding, it is difficult to correctly evaluate the past sin2Φ method. Therefore, a variety of new measurement methods have been proposed for assessing such stress distribution. Shown in this study
