本文用中子衍射法测量了厚壁钢管自增强前后切环的残余应力。概述了中子衍射的原理，并描述了中子衍射的方法。与使用更传统的萨克斯钻孔技术获得的结果进行了比较。结果表明，这两个程序之间取得了令人满意的协议，中子衍射法可以使用可接受的精度来测量几厘米厚的钢的大块样品中的残余应力非破坏性。
Abstract A neutron diffraction method has been applied to measure residual stresses in rings sliced from as-recieved and autofrettaged thick-walled steel tubing. The principles of neutron diffraction are outlined and the method is described. A comparison is made with results obtained using the more traditional Sachs boring technique. It is shown that satisfactory agreement is achieved between the two procedures and that the neutron diffraction method can be used with acceptable accuracy to measure residual stress non-destructively in bulk samples of steel several centimetres thick.
