一种利用X射线测量含织构材料残余应力的方法，涉及一种无损检测方法。钢铁、铜、铝等板带材在加工完成后，表面会产生较大的残余应力。由于织构的存在，导致经典的应力分析中ε_ψΨ-sin²ψ间失去线性关系，使采用X射线测应力法的工作变得十分困难。本发明针对含强织构的板带材工件，首先测试工件的织构类型和体积百分比，然后测量对应取向下的杨氏模量和晶格畸变，再利用dψ-sin²ψ在强取向处可保持较窄的线性关系(如图1所示)，反推具有加权意义的杨氏模量和点阵畸变，最终计算获得具有强织构板带材的残余应力。本发明为具有强织构的板带材，提供了一种简便利用X射线测残余应力的方法。

A method for measuring the residual stress of a textured material by using X-rays relates to a non-destructive testing method. After the steel, copper, aluminum and other plates and strips are processed, large residual stresses will be generated on the surface. Due to the existence of the texture, the linear relationship between ε_ψΨ - sin²ψin the classical stress analysis is lost, making the work of using the X-ray stress measurement method very difficult. The present invention is aimed at the plate and strip workpiece with strong texture. First, the texture type and volume percentage of the workpiece are tested, and then the Young's modulus and lattice distortion under the corresponding orientation are measured, and then dψ - sin²ψ can be maintained at the strong orientation. Narrow linear relationship (as shown in Figure 1), inversely calculate the weighted Young's modulus and lattice distortion, and finally calculate the residual stress of the strip with strong texture. The invention provides a simple and convenient method for measuring residual stress by using X-rays for plate and strip materials with strong texture.
