Abstract
Because of the intensive research work in a system RE-TM three so called new generations of permanent magnetic materials wire discovered in the last two decades. The purpose of the proposed project is to continue the basic research in the systems RE2TM17NY, RETM5 and RE2TM14B. The research work will be emphasised in studying the chemical composition and preparation methods on the phase composition, microstructure and consequently on the final magnetic properties. The influence of additives specially Zr and ZrO2 on the magneic anisotropy of the HDDR processed material will be studied. HDDR, as a very promising processing route for the preparation of the nanocrystalline magnetic powders, will be used also as a preparation method for nanocrystalline powders of the perspective alloys.
