Summary on Grant Application Form
The development of new techniques to measure a materials microstructure either to better accuracy or in conditions where measurement has not been possible before can lead to a dramatic improvement in the understanding of the material, its processing and hence the ability to control its properties. The majority of microstructural analysis techniques are destructive and / or require small samples and are thus limited in applicability if dynamic analysis in-situ during commercial processing is of interest. Several techniques have been proposed to directly measure microstructures, and Electromagnetic (EM) sensors are proven to be particularly well suited to harsh production environments. This project will further the understanding of the relationship between electromagnetic sensor outputs and microstructure. Recent results have indicated that the technique is more powerful than originally anticipated. The feasibility of accurately measuring on-line phase transformation and material grain size above and below the Curie temperature using non-contact instrumentation will be explored. In addition the exciting prospect of being able to measure a 3-D microstructure, in terms of grain size, by using a multi-frequency sensor array and the potential spin-off application of a non-destructive measurement technique of decarburisation will be investigated.
