X-ray stress analyzer

DST-17 X-ray Stress Analyzer

The DST-17 X-ray stress analyzer provides the most reliable means of testing materials and their products. Residual stress and texture can be accurately measured for multi-domain material structures and irregularly shaped parts.

The instrument is characterized by high power, high resolution and accurate measurement results.

High-precision diffraction angle measuring device for the most accurate 2θ angle

Both iso- and side-inclination methods can achieve residual stress

Automatic conversion of stress measurement in the X and Y directions at the same point to achieve tangential stress measurement

Arbitrarily set the point of sample, automatically complete the residual stress measurement, and draw the stress distribution map

High-resolution SDD detector for residual stress measurement of various materials when the target is fixed

Simultaneously configure Si drift line array detector to quickly complete residual stress measurement

α angle range is large, measure pole figure by side-inclination method

Built-in laser ranging locator for automatic positioning of samples with repeatability less than 3μm

CCD camera, laser calibration, 5D hand crank control, simplify manual positioning
