  • X-Ray Stress Analyzer: Working Principle, Structure, and Key Technologies
    X-Ray Stress Analyzer uses X-ray diffraction to non-destructively measure surface residual stress, critical for fatigue and corrosion resistance. Based on Bragg's Law, it detects stress by measuring crystal lattice strain via diffraction angle shifts. Key components include a stable X-ray generator, a high-precision goniometer (0.001° accuracy), advanced detectors, and specialized software. It transforms atomic-scale changes into essential engineering data for material safety.
