定向凝固的镍基合金和硅、锗单晶以及取向硅钢等强织构材料的精确定向和宏应力计算一直是材料领域十分关注的问题,本文采用了一种基于单一极图识别晶体坐标系取向的方法,直接利用宏应力测算中的极角参数来确定晶体坐标系的欧拉角;讨论了将该方法和Suyama等人提出的宏应力X光衍射回归分析方法相结合的算法,使该方法更易于工程应用。 Directional solidification of nickel-based alloys and silicon, germanium single crystal and oriented silicon steel and other strong textured materials, precise orientation and macro-stress calculation has been a matter of great concern in the field of materials, this paper uses a single polar pattern recognition crystal coordinate system orientation Method to directly determine the Euler angles of the crystal coordinate system by using the polar parameters in the calculation of macro stress. The algorithm combining the proposed method with the method of macro-stress X-ray diffraction regression analysis proposed by Suyama et al. Easy to engineering applications.
