Proven Technology

Our residual stress XRD measurement systems utilize the industry-accepted sin2ψ multiple exposure technique (MET). Time-tested and accurate, this technology is proven to be reliable and capable of handling samples with complex geometries, preferred orientation, and large grains.

Accurate Results

Other techniques, such as the cos-alpha and single exposure technique (SET), may appear to be simpler and easier to use but have many limitations. Thus, large errors can propagate into the final results. Unlike these techniques, which are hindered by both material condition and constraints in data collection, the sin2ψ method ensures a full and comprehensive data set is available to correctly calculate residual stress with low measurement errors.

You measure residual stress to satisfy performance, safety, and quality requirements. You go to extensive lengths to engineer high-quality, robust components. Proto offers the highest quality and most accurate measurement technology, ensuring your engineering efforts are not wasted.

Our residual stress measurement systems are designed to provide the most accurate results available for your parts, regardless of the geometric complexity or material. In particular, safety-critical and life-limited engineered parts need an accurate assessment of their residual stress. Don't undermine your engineering with inferior measurements.

Customization Options

Our innovative options, such as residual stress mapping, state-of-the-art detectors, advanced goniometers, and modular field stands, guarantee that the right measurement tool is available for you. Additional add-on features include pole figures, retained austenite, or nitride analysis to make your system even more powerful.
