DIFFRAC。纹理

材料和部件的性能受到固有的或应用的优选取向或结构的显著影响，这可以通过x射线衍射方法进行非破坏性研究。

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.
后者在DIFFRAC中实现。纹理, all crystal systems are now supported and the variety of sample symmetries ensures that a huge diversity of textures can be handled.

• 直接从0D, 1D和2D测量数据创建极点图，只需单击分配到晶体相。
• 基于全细节模型的纹理分析构件法。
• 直接计算方位分布函数的球面谐波法。
• 强大的纹理表示能力和广泛的报告生成器。

从实测数据生成磁极图从未像现在这样容易。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includes powerful tools and options for a more detailed analysis of the obtained textures:

• odf可以用3D或一组2D切片来计算和表示。
• 沿表面法线方向、面内滚动方向和横向方向的反极图。
• 各个纹理组件的3D可视化，以支持更好地理解它们的方向。
• 各组分体积分数的饼状图表示，包括各向同性含量。

的球面谐波法是一种无模型方法如果方向分布函数是最重要的，选择的方法。

ODF直接由测量的极点图形的一系列展开计算，使用一组定义在球面上的特殊函数-广义球面谐波。

该方法的优点是它以ODF的形式快速、简单地提供了纹理结果，不需要太多的先验样本知识。
