Principles and Applicability of Portable XRD Residual Stress Analyzers Using Single Exposure cosα Method
摘 要
对市场上近几年出现的便携式单次入射cosα法X射线衍射残余应力分析仪进行了深入研究，详解其原理，具体分析了在二维平面和三维应力状态下cosα法的算法依据，评估了该方法在材料存在粗晶、不平表面、织构和应力梯度等非线性关系时的适用性，与国际和国内现行的sin2ψ法进行了测量结果对比，实地考察了仪器的对焦以及准直器和X射线管更换的便捷性等情况，对该cosα法应力分析仪的优缺点及适用性提供了科学、客观的评判依据。

Abstract
A comprehensive study was carried out on portable XRD residual stress analyzers using single exposure cosα method promoted in recent years, and the principles were explained in detail. Algorithms of 2-dimensional and 3-dimensional stress states were analyzed. The applicability of the method was evaluated when there were nonlinear relationships in materials such as coarse crystal, curved surface, texture and stress gradient. Measurement results using cosα and sin2ψ methods according to international and domestic standards were compared, and conveniences of instrument focusing and replacement of collimator and X-tubes were investigated. A scientific and objective basis to evaluate merits, demerits and applicability of the stress analyzer using cosα method was provided.
