High entropy alloys (HEAs) are a novel class of material that have highly tailorable properties depending on their composition. In addition to the ability to tailor their properties, they can also be functionally graded enabling the joining of two dissimilar materials that would otherwise be difficult or detrimental to place in contact with each-other (a good example being Fe and Al). Coatings are being applied to accident tolerant fuels to improve their behaviour during an accident, for example a loss-of-coolant accident, reducing the corrosion rate and likelihood of fuel failure. This exciting project will highlight the potential for HEA use in water reactors and beyond, collaborating with other institutions, both nationally and internationally, focused on producing accident tolerant fuel cladding materials.This industrially focused project will combine a cutting edge atomic scale modelling methodology with targeted experiments to advance the field. The project will be highly industrially focused with the successful candidate being expected to present within a number of international consortia.

高熵合金（HEAs）是一种新型材料，根据其组成具有高度可定制的性能。除了能够定制它们的特性之外，它们还可以是功能梯度的，使得能够连接两种不同的材料，否则这两种不同的材料将难以或不利于彼此接触（一个很好的例子是Fe和Al）。目前正在对耐事故燃料进行涂层处理，以改善其在发生事故（例如冷却剂损失事故）时的性能，降低腐蚀速度和燃料失效的可能性。这个令人兴奋的项目将突出HEA在水反应堆及其他领域的应用潜力，与国内和国际上的其他机构合作，专注于生产事故容限燃料包壳材料。这个以工业为重点的项目将联合收割机结合尖端的原子尺度建模方法和有针对性的实验，以推动该领域的发展。该项目将高度集中在工业领域，成功的候选人将在一些国际财团中出现。
