雷竞技网页版材料和组件的性能受到固有的或应用的优选取向或纹理的显著影响,可以通过x射线衍射方法进行无损研究。
DIFFRAC。纹理is the powerful and easy-to-use software suite designed to analyze texture measurements. By utilizing a systematic approach to analysis according to a flowchart, DIFFRAC.TEXTURE delivers comprehensive texture information with just a few mouse-clicks.
DIFFRAC。纹理features two well established and complementary techniques to provide the most accurate and reliable results: the model independent Spherical Harmonics methods and the model dependent Component Method.
在DIFFRAC中实现了后者。纹理, all crystal systems are now supported and the variety of sample symmetries ensures that a huge diversity of textures can be handled.
从测量数据中生成极点图从未如此容易。DIFFRAC。纹理can import data measured with 0D, 1D or 2D detectors and instantly create pole figures with single click operation either from selected angular regions (1D) or directly from 2D frame stacks via a single frame-cursor selection.
DIFFRAC。纹理comes with a comprehensive crystal structure database that allows linking of pole figures to the corresponding hkl reflections with the least effort. Overlapping signals from different phases can be easily assigned to facilitate data analysis.
DIFFRAC。纹理features two complementary and powerful analysis methods that deliver accurate and reliable results:
模型无关的球面谐波方法直接从极点图计算方向分布函数(ODF),只需单击一次鼠标。
组件方法是一种基于模型的方法,它使用快速和健壮的最小二乘优化将一组纹理组件匹配到极点图形。
DIFFRAC。纹理includes powerful tools and options for a more detailed analysis of the obtained textures:
的球面谐波法是一种无模型的方法和选择方法,如果方向分布函数是主要的兴趣。
ODF直接从测量极点图的一系列展开中计算,使用定义在球体表面上的一组特殊函数-广义球面谐波。
该方法的优点是可以快速简单地以ODF的形式提供纹理结果,不需要太多的先验样本知识。
的组件方法是一种基于模型的方法纹理是由一组描述样品[1]部分的方向、晶体和工艺对称性的组件建模的。从这些纹理分量中计算出相应的极点图。
然后利用鲁棒最小二乘优化方法将模拟极点图与实测极点图进行拟合,从而细化各分量的参数。
组件方法提供了对纹理的更深入的了解:纹理组件的过程对称性将样品的制造和加工与测量的极点图形联系起来。
