The aim of this project is to prepare iron-based magnetic nanostructures that exhibit a magnetic induction of 1.9 tesla and core losses lower than those of iron-silicon steels, which would deliver smaller and efficient magnetic cores for petrol-electric hybrid cars. Preliminary results from the research team show that iron-metalloid alloys with an iron content of 87 per cent meet this magnetic induction with room for further improvement of magnetic softness. The project aims to systematically investigate the effect of metalloid and micro-alloying elements on the nano-crystallisation behaviour of the precursor amorphous alloys in order to identify the alloy composition and processing conditions for preparing magnetically soft nanostructures.

该项目的目的是制备铁基磁性纳米结构，其磁感应强度为1.9特斯拉，磁芯损耗低于铁硅钢，这将为油电混合汽车提供更小和更高效的磁芯。研究小组的初步结果表明，铁含量为87%的铁-准金属合金满足这种磁感应强度，但磁柔软度还有进一步提高的空间。该项目旨在系统地研究准金属和微合金化元素对前体非晶合金纳米结晶行为的影响，以确定制备软磁纳米结构的合金成分和加工条件。
