Residual stresses are of key importance across all industrial sectors where metals are used e.g. within the transportation and energy sectors.
Reliable evaluation of residual stresses plays a key role in quality control but is challenged by materials properties and technique limitations. Methods being widely adopted in industries for residual stress measurement are mostly destructive and/or surface-only. Non-destructive, bulk measurement techniques such as synchrotron X-ray and neutron diffraction have not yet gained a foothold in industry due to a lack of validation and standards. However, these techniques can be used to qualify new materials or processes to reduce the time-to-market. The European Activity for Standardisation of Industrial Residual Stress Characterization (EASI-STRESS, Project duration from 01/2021 to 06/2024) conduscted round robin activities aimed at building the path to promote industrial access to these non-destructive stress characterization tools by harmonizing these techniques against more accepted lab techniques.

In this contribution we show the results of the EASI-STRESS project and focus on examples of residual stress analysis performed on components provided by the industry partners in the project consortium. We will adress the challenges these particular samples contained for the research infrastructures and give an outlook on further activities and the standardisation process.
