This proposal focuses on materials discovery and design based on investigations of novel inherently nanolaminated MAX and MAB phases, which offer various possibilities for nanoscale engineering through simultaneous control of structure and composition. High-throughput synthesis in form of thin film multinary materials libraries will be employed for systematic efficient exploration of the inherently nanolaminated materials space in search for new phases with novel structures and improved properties, also motivated by their potential for subsequent transformation into 2D counterparts. New ternary MAX and MAB phases and alloys thereof will be addressed, with particular focus on ordered quaternary alloys and multinary (high-entropy-like) compositions for improved magnetic properties. A novel synthesis technique, targeted element replacement, will also be utilized. This research program will not only expand the families of MAX and MAB phases with a range of new ternary members and alloys in between, represented by multi-dimensional property diagrams for systematic data evaluation and comparison, but will also establish multinary alloying and combinatorial synthesis approaches which to date have been very little explored for this class of materials.

本提案的重点是基于对新型固有纳米层化MAX和MAB相的研究来发现和设计材料，这些相通过同时控制结构和成分为纳米级工程提供了各种可能性。薄膜多材料库形式的高通量合成将用于系统有效地探索固有的纳米层化材料空间，以寻找具有新颖结构和改进性能的新相，也受到其随后转化为2D对应物的潜力的激励。将讨论新的三元MAX和MAB相及其合金，特别关注有序季元合金和用于改善磁性能的多元（高熵类）成分。一种新的合成技术，靶向元素置换，也将被利用。该研究计划不仅将扩展MAX和MAB相的家族，其中包括一系列新的三元成员和合金，由多维性能图表示，用于系统的数据评估和比较，而且还将建立迄今为止对这类材料很少探索的多元合金和组合合成方法。
