Final report
Publication metadata
Materials are ageing due to many different causes; e.g. thermal treatment, stress ageing, corrosion, irradiation embrittlement, etc. The different causes, and their synergism, are acting on the materials in many different ways, e.g. vacancies generation and dislocations, migration of low melting temperature metals to the grain boundary, matrix damage, etc. Each cause, even though by mean of different mechanisms, is responsible for the embrittlement of the material making it more prone to rupture. The assessment of material ageing requires normally extensive destructive testing by using different kind of testing and samples. A non-destructive determination of the embrittlement state would extend the usefulness of the surveillance material by reducing the material used for destructive studies and would benefit surveillance programs having an insufficient amount of available test material, and ultimately allowing tests to be performed directly on the component to evaluate. Such NDE capabilities would provide substantial early warning of component deterioration and enable utilities to optimise their operating and maintenance practices, resulting in reduced costs and increased asset utilisation. The possibility to qualify Non-destructive Techniques, NDT, at least for some of the above mentioned ageing cases, would make the assessment of ageing much easier and cheaper, saving a lot of money and resources in Europe. Furthermore, it would make it possible to assess on field various components that now-a-day can only be assessed either by calculation or by means of very expensive sample gaining techniques.
