Abstract:
A critical evaluation has been carried out on non-invasive techniques for the detection of damage and the characterisation of microstructural changes that occur during the life cycle of materials from processing through to in-service operation. The techniques were grouped into 8 different categories. This review does not present the theory and full operation of the techniques in great detail, but notes their strengths and weaknesses and their range of application. This review is carried out from a generalistÂ’s point of view and keeps foremost in mind the likely usefulness of individual techniques to the current and projected work carried out in the Division of Engineering and Process Control of the National Physical Laboratory. A short list comprising one candidate technique for damage assessment and four candidates for microstructural evaluation is presented.
