The technology and application of residual stress analysis by neutron diffraction

中子衍射方法可以用来测量材料内部的三维残余应力分布,是一种重要的无损检测分析手段。本文概述了中子衍射残余应力分析的基本原理、特点和发展现状,并简要介绍了其在工程和材料科学领域的应用情况与前景。

Neutron diffraction, an important non-destructive testing method, can facilitate 3-D mapping of residual stress in a bulk component. In this paper, the principle, characteristic and developed status are described about the analysis of residual stress by neutron diffraction. The application of the technique in engineering and material science research is also briefly introduced.
