The PureAlloys project will advance our understanding in the nature of the Cosmos by enabling novel, extremely radiopure,experimental searches for Dark Matter and for neutrinoless double beta decay. Current experiments are constrained by radioactivecontamination in the detector manufacturing process, posing the main barrier in their physics discovery potential. Electroformedcopper achieves extreme radiopurity, however it is limited by its mechanical properties: high ductility and low strength. PureAlloyswill address this challenge by designing high radiopurity CuCr and CuCrTi alloys with significantly higher strength. A novel multi-scalemodelling framework enabling fast progress in designing application-specific alloys will be developed, opening the path for thedesign of new alloys in fields involving fabrication and properties enhancement where the thermodynamic and kinetic description ofthe system is crucial. PureAlloys will push the boundaries in many fields: from fundamental science to industrial applications.

PureAlloys项目将通过实现对暗物质和无中微子双β衰变的新颖的、极其不透射线的实验性搜索来推进我们对宇宙本质的理解。目前的实验受到探测器制造过程中的放射性污染的限制，这是其物理发现潜力的主要障碍。电铸铜实现了极高的放射性纯度，但它受到其机械性能的限制：高延展性和低强度。PureAlloys将通过设计具有更高强度的高放射性纯度CuCr和CuCrTi合金来应对这一挑战。一个新的多尺度建模框架，使快速的进展，在设计应用特定的合金将被开发，开辟道路，设计新的合金领域涉及制造和性能增强的热力学和动力学描述的系统是至关重要的。PureAlloys将推动许多领域的边界：从基础科学到工业应用。
