X-ray diffraction (XRD)

DIFFRAC. TEXTURE

On the use of zero dimension, one-dimensional or two-dimensional detector to collect the texture of powerful software of data collection and analysis of data sets.

Bright spot

Comprehensive analysis of the texture function, simple and easy to use

Internal or man-made preferred orientation or texture, to effect the performance of materials and components, and study the X ray diffraction method can condition texture.

DIFFRAC. The TEXTURE is a powerful and easy-to-use software package that is suitable for the analysis of TEXTURE measurement data.Analysis by using the method of system according to the flowchart, simply clicking a mouse DIFFRAC. TEXTURE can get integrated TEXTURE information.

DIFFRAC. TEXTURE USES two kinds of perfect and complementary technology, can provide the most accurate and reliable results, independent of the model of spheric harmonic function and depends on the components of the model.

DIFFRAC. The TEXTURE of the latter method can support all crystal system, symmetry and extensive sample to ensure it can handle a wide variety of TEXTURE.

  • After matching phase, zero, one and two dimensions measurement data can be directly mapped polar diagram.
  • Based on complete detailed model component method is suitable for the analysis of the texture.
  • Spheric harmonic function method is applicable to directly calculate the orientation distribution function.
  • Powerful texture characterization and extensive report generation process.

The characteristics of

Texture analysis process

1. Define data import and samples

Data import and polar diagram generation

Using the measurement data generated figure had never been so easy.DIFFRAC. TEXTURE可以导入利用零维、一维或二维探测器测得的数据,根据对一维或二维数据选定的角度区域,单击鼠标即可快速生成极图。

DIFFRAC. TEXTURE provide a comprehensive, the crystal structure of database can be easily match extremely figure with corresponding HKL reflections.Can be easily assigned from different phase of overlapping signals, to facilitate data analysis.

2. The polar diagram analysis

Texture analysis of pole figure

DIFFRAC. TEXTURE USES two kinds of perfect and complementary technology, can provide the most accurate and reliable results:

Just click the mouse, independent of the model of spheric harmonic function method can be calculated directly from pole figure orientation distribution function (ODF).

Component method is a kind of method based on the model, can be based on fast and robust least squares will be a corresponding organization structure and the pole figure.

3. The texture characterization

Through the ODF texture characterization

DIFFRAC. TEXTURE contains powerful tools and to obtain the TEXTURE of a detailed analysis of options:

  • You can calculate the ODF, and a group in the form of a 3 d or 2 d slice.
  • Along the surface normal direction and plane in rolling direction and transverse direction of inverse pole figure.
  • Of 3 d visualization, the single texture to facilitate a better understanding of their sexual orientation.
  • With the pie chart shows that the volume fraction of components, including the isotropic component.

Two methods of texture analysis

Spheric harmonic function method

In the form of a two-dimensional display spheric harmonic function method is used to obtain the orientation distribution function.

Spheric harmonic function methodIs a need to model method, the most suitable for the main research object is the orientation distribution function.

ODF is to use a set of special function of the definition of the sphere, by measuring the series expansion of the polar diagram directly calculated, the generalized harmonic function.

The advantage of this method is that it can be easy to quickly provide in the form of the ODF texture as a result, without having to have a lot of understanding of the sample.

Components method

DIFFRAC. TEXTURE - component method is used for TEXTURE analysis

Components methodIs a kind of method: based on the model described by a set of part of the orientation of the sample, symmetry of the crystal and process components, the texture model [1].Through these texture components to calculate the corresponding figure.

Then, using improved least-square optimization simulation extremely figure with measuring pole figure fitting, to improve the parameters of the components.

Component method can be used for deeper understanding of the texture, the texture components technology symmetry can sample production and processing with measuring polar diagram.
