Residual stress in the surface layer of the sample is measured non-destructively using a residual stress measurement device.
We will conduct stress measurements on the surface of polycrystalline materials using an X-ray residual stress measurement device. Stress measurement utilizing the principle of X-ray diffraction is widely used in material development and quality evaluation of products. Measurements with this equipment allow for non-destructive, micro-area, high-precision, and quick residual stress assessments.

basic information
【Non-destructive measurement is possible】 Since it utilizes the principle of X-ray diffraction, there is almost no damage to the sample. It is possible to measure products that should not be scratched and to measure changes in stress at each process of the same product. 【Depth measurement is possible】 By etching with an electrolytic polishing device, the stress distribution in the depth direction can be measured. 【Local measurement is possible】 Measurement of small areas (up to φ150μm with collimator size) is possible. Pinpoint measurements can be made in local areas where strain gauges cannot be used. 【Teaching measurement is possible】 By programming the measurement position and conditions with the teaching function, automatic measurement is possible. This significantly reduces the measurement time for multiple samples. 【Measurement of large heavy samples is possible】 A sample horizontal goniometer that keeps the sample stationary is adopted, accommodating maximum sizes of φ320mm × 215mm and weights up to 20kg. 【Quantification of residual austenite is possible】 It can quantify the residual austenite in the surface layer of steel materials using the principle of X-ray diffraction.
