Using the principle of X-ray diffraction, residual stress in the sample is measured non-destructively.
The residual stress measurement service utilizes the principle of X-ray diffraction to measure the stress in the surface layer of polycrystalline materials. Stress measurement can be utilized in a wide range of fields, including the calculation of strength based on the shape and safety of products during the development, prototyping, and production stages, as well as the establishment of processes to maintain that strength.

basic information
【Non-destructive Stress Measurement】 Measurements can be performed using X-rays, allowing for non-destructive and low-damage assessments. 【Depth Direction Stress Distribution Measurement】 By etching with an electrolytic polishing device, it is possible to measure the stress distribution in the depth direction (depth profile). 【Micro-area Stress Measurement】 Measurements can be conducted in micro-areas up to φ150μm in size using a collimator. 【Short Delivery Time Support】 With the PSPC detector enabling simultaneous measurements over a wide range of angles, fast measurements can be achieved in a short time. 【Support for Mapping and Teaching Measurements】 High-precision XYZ stages allow for XYZ mapping and teaching measurements. 【Stress Measurement of Large Heavy Samples】 With a sample horizontal goniometer that holds the sample in place and our own heavy-duty sample stage, we can accommodate samples up to a maximum size of φ320mm×215mm and weighing up to 20kg. (*The automatic stage that supports mapping and teaching measurements is limited to 10kg.)

Company information
Our main business is providing technical services to evaluate the reliability of developed products. We not only provide evaluation data in accordance with standards and regulations, but also propose optimal methods, conditions, and equipment for evaluation purposes, as well as design and manufacture original equipment and jigs for non-standard evaluations. Additionally, we handle three evaluation techniques—measurement, testing, and analysis—comprehensively, allowing us to offer complex services that span diverse equipment and suggest more multifaceted evaluation methods.
