Hydrogen is used in the conventional production of sintered (rare earth) neodymium-iron-boron magnets and in the recycling of these materials. The University of Birmingham has led international efforts in both of these areas. In recent years the Magnetic Materials Group have been developing new methods to manufacture rare earth magnets based on a process called hydrogen ductilisation. This process involves heating cast alloys in hydrogen to modify the microstructure. The material which is produced is ductile and can be shaped at room temperature. This reduces the number of process steps, reduces waste and could give a significant economic advantage to magnet manufacture. However the process is far from optimised and the aim of this project will be to develop this process alongside the team in Birmingham.

氢气用于烧结（稀土）钕铁硼磁体的常规生产以及这些材料的回收。伯明翰大学在这两个领域都引领了国际努力。近年来，磁性材料集团一直在开发基于氢延展工艺的稀土磁体制造新方法。该过程涉及在氢气中加热铸造合金以改变微观结构。所生产的材料具有延展性，可以在室温下成型。这减少了工艺步骤的数量，减少了浪费，并且可以为磁体制造带来显着的经济优势。然而，该流程远未优化，该项目的目标是与伯明翰团队一起开发该流程。
