Summary on Grant Application Form |
|
NdFeB-type alloys can be processed to produce excellent permanent magnet materials. However, the properties of the resulting magnet are not intrinsic to the material but depend crucially on the interplay between detailed composition, the processing conditions employed and the microstructure that results. Here we intend to use state-of-the-art processing facilities that exist at Birmingham University and state-of-the-art facilities for high spatial resolution characterisation of magnet and physical microstructure at Glasgow University to increase our understanding of how processing and composition effect the microstructure of the materials under study. Using the knowledge so gained we then intend to optimise permanent magnet properties. Specifically, our studies will involve both sintered material and that produced by the hydrogenation, disproportionation, desorption and recombination (HDDR) route; elemental additions of interest will include Co, Ga, Zr and Cu. Microscopical observations will be made not only on final permanent magnet material but at key intermediate stages of the processing. It is intended that insight will be gained into the development of both anistropy and coercivity in these economically important alloys.
