In this project, SmCo-Fe and SmCo-FeCo amorphous alloys as well as SmCo amorphous matrix with a few Fe(Co) nanocrystals will be prepared by ball milling the commercial SmCo5, a-Fe and Co raw materials of powder particles in micrometer. These amorphous materails will be deformed and crystallized under temperature gradient environments. The crystallization kinetics, nanocrystalline phase formation and evaluation, nanocrystal nucleation and growth in the SmCo amorphous alloys suffered hot-deformation processings under temperature gradient will be studied. The effect of temperature gradient on the preferential growth of SmCo nanocrystals in the hot-deformed alloys will be investigated in details. In addition, we will also study the effect of preexisted Fe(Co) nanocrystals in amorphous matrix on crystallization kinetics, nanocrystal nucleation and preferential growth as well as the microstructures of the deformed alloys. Moreover, the conditions for yielding preference growth of SmCo nanocrystals under temperature gradient in the hot-deformed alloys and their microstructure characteristics will be achieved. The effect of microstructure of amorphous alloys on the preferential growth of SmCo nanocrystals will also be investigated. Furthermore, the relationship between thermo-mechanical processing parameters (i.e., deformation temperature, strain and strain rate), microstructures and magnetic properties of the hot-deformed alloys will be investigated in details. Based on these studies, anisotropic bulk SmCo/Fe(Co) nanocomposite magnets with excellent properties will be produced. The present study is of importance for the development of bulk anisotropic nanocomposite magnets.
