The multi-functional residual stress analyzer developed by Dandong Tongda Technology Co., Ltd. is designed to meet the needs of fast and accurate measurements in both laboratory and field environments. Based primarily on the X-ray diffraction principle, it enables non-destructive testing of the residual stress state inside materials.
Versatile All-in-One Analysis
This analyzer integrates multiple material analysis functions, significantly enhancing equipment utility and efficiency:
Residual Stress Analysis: Supports various measurement modes such as standard同倾法 (omega-inclination), standard侧倾法 (psi-inclination), and standard摇摆法 (oscillation), capable of determining principal stresses and shear stresses for a comprehensive stress state evaluation.
Retained Austenite Analysis: Employs the four-peak method for retained austenite testing, with fully automated data calculation for quick results.
Diffraction Phase Analysis: Used to analyze crystal structures, chemical composition content, and distribution, helping researchers gain deeper insights into material constitution.
Grain Size Analysis: Supports grain size evaluation from nanoscale to sub-micron scale, particularly suitable for fine grains ≤200 nm.
Technical Features and Performance
This instrument boasts multiple technical features aimed at ensuring precision, stability, and ease of use:
High-Precision Measurement and Control: Utilizes a high-precision fully closed-loop vector drive servo system to ensure measurement accuracy and repeatability.
Efficient Data Acquisition: Equipped with a multi-channel silicon strip linear array detector, which provides noise-free performance, high-intensity measurement, and rapid data collection to enhance detection efficiency.
Portable Design: Features a lightweight construction, making it suitable not only for laboratory environments but also for on-site rapid measurements, adapting to various testing scenarios.
User-Friendly Operation: Integrates Windows OS or automation functions, supporting one-click testing and real-time result display, lowering the operational barrier.
