局部屏蔽法在X-Ray残余应力测量中的应用

Application of Local Covered X Ray Technique to Residual Stress Measurement

本文所述的局部屏蔽法即是在Ｘ射线测量过程中的下遮挡法，即是将被测部位暴露出来，而将其余部位进行遮挡以对Ｘ射线进行屏蔽。局部屏蔽法是解决应力梯度测量中的一种有效方法。

The local covered X ray technique used in the process of residual stress measurement is a technique means that the concerned area is exposed and the rest of area can be screened from X ray.This technique is an efficient method for measuring the area with stress gradient.The key technique is presented in this paper and good results are obtained.
