摘　　要：介绍了短波长特征X射线衍射无损检测分析原理和方法,无损地测定了预拉伸铝板、高强钢孔挤压件、铝合金搅拌摩擦焊接件等材料部件的内部残余应力、内部物相、内部织构及其分布,并分析讨论了测试结果。该仪器具有体积小,投资少、使用维护方便等优势,展望了该无损检测分析技术在装备环境工程中的应用前景。This paper introduced analysis principles and methods for nondestructive testing of short-wavelength X-ray diffractometer （SWXRD）. The nondestructive testing includes internal residual stress, internal phase, internal texture and their distribution of in aluminum alloy pre-stretch plate, cold hole expansion parts of high strength steel, aluminum alloy weldments, etc. The test result was analyzed and discussed in the paper. The instrument is featured with advantages such as small size, low investment and easy maintenance, etc. The application of SWXRD was prospected in equipment envi- ronmental engineering.
