The development of new techniques to measure a materials microstructure in conditions where measurement has not been previously possible can lead to a dramatic improvement in the understanding of the material, its processing and hence the ability to control its properties better. At present, the majority of microstructural analysis techniques are destructive and / or require small samples. Consequently, they are limited in applicability if dynamic microstructural analysis in-situ during commercial processing is of interest. A number of techniques have been proposed to directly measure microstructures on-line during processing but as yet no single technique appears to offer a full solution.The metals industry is highly competitive and the ability to adapt to the changing demands of customers is essential, e.g. via introduction of new products. There is also a need to produce high quality (high added value) products in order to keep a competitive edge in the global economy. This in turn requires new and better measurement and control procedures and therefore an on-line inspection system would be highly valuable.The aim of the MAIS project has been to exploit novel multi-frequency electromagnetic techniques to analyse microstructure. The research has involved theoretical analysis of the response to ferrite fraction and morphology and the electromagnetic properties of steel, which has been supported by 3D modelling of both simple and realistic microstructures. In parallel, the problem of inverting the complex inductance spectra acquired by the sensor system to yield parameters of metallurgical significance has been addressed. Finally, sensor configurations which can be deployed on-line have been considered.This follow on project (AMAIS) will demonstrate the efficacy of the electromagnetic microstructure analysis system in a real industrial environment and prove that the technology developed over two previous EPSRC projects in partnership with the metallurgy experts in industry and academia can be taken from the laboratory to real application. The Follow on Fund is also important to ensuring a strong IP position as the technology moves forward.

在以前无法测量的条件下测量材料微观结构的新技术的发展可以导致对材料的理解，其加工以及更好地控制其性能的能力的显着改善。目前，大多数显微结构分析技术是破坏性的和/或需要小样品。因此，如果在商业加工过程中原位动态微观结构分析是有意义的，则它们的适用性有限。许多技术已经被提出来直接在线测量加工过程中的微观结构，但迄今为止还没有一种技术能够提供完整的解决方案。金属行业竞争激烈，适应客户不断变化的需求的能力至关重要，例如通过推出新产品。还需要生产高质量（高附加值）产品，以便在全球经济中保持竞争优势。这反过来又需要新的和更好的测量和控制程序，因此，在线检测系统将是非常有价值的。迈斯项目的目的是开发新的多频电磁技术来分析微观结构。该研究涉及对铁素体分数和形态的响应以及钢的电磁性能的理论分析，这得到了简单和现实微观结构的3D建模的支持。与此同时，反演复杂的电感频谱传感器系统获得的冶金意义的参数的问题已经得到解决。最后，传感器的配置，可以部署在on-line已被认为是。这个后续项目（AMAIS）将证明电磁微观结构分析系统在真实的工业环境中的功效，并证明了技术开发超过两个以前的EPSRC项目在工业和学术界的冶金专家的合作伙伴关系，可以从实验室到真实的应用。随着技术的发展，后续基金对于确保强大的知识产权地位也很重要。
