  • X-Ray Diffraction (XRD) Analysis

    X-ray diffraction analysis is the main method to study the phase and crystal structure of substances. When a substance is subjected to diffraction analysis, the substance is irradiated by X-rays to produce different degrees of diffraction. The material composition, crystal form, intramolecular bonding mode, molecular configuration, conformation and so on determine the unique diffraction pattern of the material. X-ray analysis is a modern method for material structure and composition analysis, which has the advantages of no damage to samples, no pollution, high speed and high degree of measurement. As a professional reliability third-party testing organization, T,C&A Lab can perform X-Ray Diffraction Analysis according to ISO, ASTM and other standards. Welcome to contact our experts for consultation.

    Our X-ray diffraction method can help you

    • Phase identification

    Phase identification refers to the determination of which phases the material is composed of and the content of each phase, which mainly includes qualitative phase analysis and quantitative phase analysis.

    • Determination of lattice parameters

    It is often used to determine the solid solubility curve of the phase diagram.

    • Determination of macroscopic stress

    The direction and magnitude of macroscopic residual stress directly affect the service life of machine parts. By measuring the distance between the lattice planes in different directions, the magnitude and direction of the residual stress can be calculated.

    • Determination of crystallinity

    Crystallinity is an important parameter affecting material properties.

    • Characterization of particle size of nanomaterials

    The average particle size of nanoparticles can be determined by X-ray diffraction line width method.

    • Determination of crystal orientation and texture

    The determination of crystal orientation, also known as single crystal orientation, is to find out the orientation relationship between the crystallographic orientation in the crystal sample and the external coordinate system of the sample.

    Standards we test to

    ASTM E2860Standard Test Method for Residual Stress Measurement by X-Ray Diffraction for Bearing Steels
