This proposal is part of the Paketantrag “Physical Properties of Complex Metallic Alloys (PPCMA)”. The Paketantrag addresses Complex Metallic Alloys (CMAs) as a novel field in materials science with the primary goal to determine and understand the physical properties of a wide range of CMA phases. The Paketantrag scientifically complements the European Network of Excellence “Complex metallic alloys”. In the framework of the present proposal we will continue developing a well-defined high-quality materials basis for experimental investigation. We will develop growth routes for the production of single crystals of highest structural quality of a size large enough for the application of most experimental methods in order to investigate the intrinsic physical materials properties, and we will produce materials in singlephased, polycrystalline form. The materials to be grown are selected such that a maximum knowledge gain can be expected. On the one hand we take care to provide a wide spectrum of CMA materials, covering different structure types, degrees of complexity, and element content, and on the other hand, we take care to include materials with specific relationships, e.g. isostructural phases in different alloy systems, or varying structure type at identical local order, which allow for insightful comparative studies. The materials produced will, after basic characterization, be provided for investigation to the other partners in the Paketantrag and, if required, to further collaborating partners in the European Network of Excellence “Complex metallic alloys”.

该提案是 Paketantrag“复杂金属合金的物理性能 (PPCMA)”的一部分。 Paketantrag 将复杂金属合金 (CMA) 视为材料科学中的一个新领域，其主要目标是确定和了解各种 CMA 相的物理性质。 Paketantrag 在科学上补充了欧洲卓越网络“复杂金属合金”。在本提案的框架内，我们将继续为实验研究开发明确的高质量材料基础。我们将开发生产具有最高结构质量的单晶的生长路线，其尺寸足以应用大多数实验方法，以研究内在的物理材料特性，并且我们将生产单相、多晶形式的材料。选择要种植的材料，以期获得最大的知识收益。一方面，我们注意提供广泛的 CMA 材料，涵盖不同的结构类型、复杂程度和元素含量，另一方面，我们注意包含具有特定关系的材料，例如不同合金系统中的同构相，或相同局部顺序的不同结构类型，可以进行深入的比较研究。生产的材料将在基本表征后提供给 Paketantrag 中的其他合作伙伴进行调查，如果需要，还将提供给欧洲卓越网络“复杂金属合金”中的进一步合作伙伴。
