The thermal stability of nanocrystalline alloys produced by severe plastic straining. An exciting class of materials has emerged with grain sizes two orders of magnitude finer than that produced by conventional processing. These nanocrystalline alloys are produced by intense plastic straining termed equal channel angular extrusion (ECAE).

An exciting class of materials has emerged with grain sizes two orders of magnitude finer than that produced by conventional processing. These nanocrystalline alloys are produced by intense plastic straining termed equal channel angular extrusion (ECAE). The aim of the project is to incorporate novel experimental techniques, using single crystals, in situ annealing and 3-D computer simulation to develop a fundamental understanding of microstructural stability during ECAE and subsequent thermal treatment. Such advances in our understanding of boundary mobility in fine-scale microstructures is important for evaluating their stability and, hence, the possible commercial exploitation of these materials.Read moreRead less

Summary
High performance lead-free piezoelectrics based on polar nanoregions. This project aims to enhance the electro-mechanical couplings of lead free piezoelectrics via introducing polar nanoregions for medical transducers applications. This is expected to impact on the design and development of high-performance lead free piezoelectrics, and have environmental benefits through replacing lead based counterparts.
Texture enhancement by inoculation in strip-cast metallic sheet. A recent discovery by the applicants has shown the possibility of producing, by inoculation during a direct casting route, stainless steel strip that exhibits a remarkably strong crystallographic alignment of grains perpendicular to the sheet surface.

A recent discovery by the applicants has shown the possibility of producing, by inoculation during a direct casting route, stainless steel strip that exhibits a remarkably strong crystallographic alignment of grains perpendicular to the sheet surface. The production of this so-called <001>//ND fibre texture in thin strip by direct casting represents a vastly simplified route for the possible production of iron-base strip suitable for some magnetic applications. The principle aims of the project are to elucidate the mechanisms of formation of this highly textured steel sheet and to explore the feasibility of reproducing the texture in other metallic systems.Read moreRead less

Technological advances bring demands for new engineering materials and the improvement of existing ones. Since almost every property of such materials depends directly or indirectly on matter transport, it is imperative that the materials designer can accurately predict its direction and extent. This theoretical project, supported and tested by computer simulation, will provide this knowledge. It will develop a toolbox of robust and versatile expressions for predicting and interpreting matter transport in alloy systems at high temperatures. With these expressions in hand, the designer will be in a superior position to tailor the properties of such materials.Read moreRead less
