Petrol driven cars will only be permitted for a few more years in many countries, and as a result there is a strong drive to "electrify" the automotive sector. This presents many challenges, an important one of which is to be efficient in the magnetic materials which are the heart of most electric motors. Such materials as are available currently are based upon Nd-Fe-B, with expensive additives such as Dy used to improve the magnetic stability. To avoid problems of cost and supply as electrification becomes more widespread, new magnetic materials are required, and this project will seek to discover these through guided experiments.Candidate compositions can be identified based on the likelihood of elements to mix to produce an alloy and using current understanding of magnetic behaviour to exclude certain systems. Following this, high throughput methods can be used to screen many different compositions rapidly, creating and assessing many materials in a short space of time. Such methods will be developed using the advanced equipment available at Sheffield through the Henry Royce Institute, and applied to identify promising compositions. These will then be examined in greater detail to refine their composition and microstructure, with the industrial partner facilitating testing and validation at a larger scale.

在许多国家，汽油驱动汽车的使用期限只有几年，因此汽车行业“电气化”的动力非常强烈。这带来了许多挑战，其中一个重要的挑战是如何提高作为大多数电动机核心的磁性材料的效率。目前可用的此类材料基于 Nd-Fe-B，并使用昂贵的添加剂（例如 Dy）来提高磁稳定性。为了避免随着电气化变得更加普遍而出现成本和供应问题，需要新的磁性材料，该项目将寻求通过引导实验来发现这些材料。可以根据元素混合产生合金的可能性来确定候选成分，并使用目前对磁行为的理解排除了某些系统。此后，高通量方法可用于快速筛选许多不同的组合物，在短时间内创建和评估许多材料。这些方法将使用谢菲尔德亨利·莱斯研究所提供的先进设备进行开发，并应用于识别有前途的组合物。然后将对其进行更详细的检查，以完善其成分和微观结构，并与工业合作伙伴一起促进更大规模的测试和验证。
