采用X射线衍射仪测定金属表面宏观内应力,较之X射线照相法既快又简便,其实验结果也较可靠。所以用X射线衍射仪测定金属表面宏观内应力的方法得到了普遍的应用。通常在用X射线衍射仪测定金属表面宏观内应力时,都是采用所谓的“90°～45°”法,但是这种方法其计算宏观内应力的公式较繁琐。为克服这一缺点,我们采用X射线
The X-ray diffractometer to measure the macroscopic internal stress of metal surface is faster and easier than the X-ray radiography, and the experimental results are more reliable. Therefore, the use of X-ray diffraction method to determine the macroscopic internal stress of the metal surface has been widely used. Generally, the so-called “90 ° ~45 °” method is used in the determination of macroscopic internal stress of metal surface by X-ray diffractometer. However, the formula of calculating the macroscopic internal stress by this method is cumbersome. To overcome this shortcoming, we use X-rays
