The MTA Unit specialises in the determination of residual stress using X-ray diffraction (XRD), and in the measurement of retained austenite. We can also facilitate access to other techniques available in the University of Manchester e.g. X-ray Photoelectron Spectroscopy and X-ray powder diffraction.

Residual stresses in the internal bore of a steel component

In 2004 we became the first laboratory to be accredited to ISO 17025 for residual stress determination by X-ray diffraction (XRD), and our dedicated team have been providing bespoke commercial services to the aerospace, automotive and other industries ever since. We satisfy SABRe 3 (Supplier Management System Requirements) of Rolls-Royce plc, and are an approved supplier to Rolls-Royce for this technique. In addition we have a portfolio of more than 130 other companies who have used our services. We also offer a retained austenite measurement service, principally to the rolling element bearing industry.

Backed by the extensive knowledge base of the internationally renowned University of Manchester, we offer a wealth of experience in XRD residual stress measurement that is second to none. We have performed such measurements on samples ranging in scale from a few millimetres to several metres, and from a few grams to more than a tonne. Samples can be of a curved and/or complicated geometry, and residual stresses can be determined at the surface or sub-surface, using either localised electro-polishing or acid bath immersion to remove material if required.
