Towards rare earth free permanent magnets by nanoscale phase decomposition (A04)

A04项目旨在开发一种可扩展的工艺，以获得具有更好的机械和惰性化学性质，BHmax≥30- 80 kJ/m3的非资源关键和低成本散装样品。材料是NiMn-X （X: Ga,In,Sn）复合材料和多元素高熵合金（例如comnenigaal，非化学计量L10 NiMn）（见项目B04），以利用相互竞争的AFM和FM相互作用进行磁硬化。研究结果将与项目A01、A10、B08、A11、B11相关。Z01, Z02, A01, A12， B05项目将研究其微观结构和磁性能。理论支持由B06和A07项目提供。

Project A04 aims to develop an up-scalable process to obtain non-resource critical and low-cost bulk samples with better mechanical and inert chemical properties and BHmax ≥ 30- 80 kJ/m3. Materials are NiMn-X (X: Ga,In,Sn) composite materials and multi-element high entropy alloys (e.g. CoMnFeNiGaAl, off-stoichiometric L10 NiMn) (see project B04) to exploit competing AFM and FM interactions for magnetic hardening. The results will be related to the ones of projects A01, A10, B08, A11, B11. Microstructure and magnetic properties will be investigated with projects Z01, Z02, A01, A12, B05. Theory support will be provided by projects B06 and A07.
