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.

项目A04旨在开发一种可升级的工艺，以获得具有更好的机械和惰性化学性能且BHmax ≥ 30- 80 kJ/m3的非资源关键和低成本批量样品。材料为NiMn-X（X：Ga、In、Sn）复合材料和多元素高熵合金（例如CoMnFeNiGaAl、非化学计量L10 NiMn）（见项目B 04），以利用AFM和FM相互作用的竞争来实现磁硬化。结果将与项目A01、A10、B 08、A11、B11的结果相关。将在项目Z 01、Z 02、A01、A12、B 05中研究显微组织和磁性能。项目B 06和A07将提供理论支持。
