The present proposal would allow development of systematic research efforts, which focus on the structure-property relationship in Mg-based Rare-Earth (RE) solid solution alloys of industrial importance. The studies will be carried out on binary systems, which include series of Mg-Gd, Mg-Y, Mg-Sm and Mg-Sc alloys. The proposed program assumes comprehensive studies of mechanical, electrical and microstructural properties developed during plastic deformation over the range of temperatures between 4.2K and 300K. The project will allow elucidating the contribution of different RE-elements such as Gd, Y, Sm and Sc on the properties of alloys and it will enhance our knowledge of the processes which determine strength and ductility of these materials. This knowledge can be used for the development of new alloys, with better combination of functional properties for automotive and other applications. The detailed knowledge of alloy behaviour will improve the reliability in processing operations and therefore will increase productivity in the industrial sector.

目前的提案将允许开展系统性研究工作，重点关注具有工业重要性的镁基稀土（RE）固溶体合金的结构-性能关系。研究将在二元体系上进行，其中包括Mg-Gd、Mg-Y、Mg-Sm和Mg-Sc合金系列。拟议的计划假设对 4.2K 至 300K 温度范围内塑性变形过程中产生的机械、电气和微观结构特性进行全面研究。该项目将阐明不同稀土元素（例如 Gd、Y、Sm 和 Sc）对合金性能的贡献，并将增强我们对决定这些材料的强度和延展性的过程的了解。这些知识可用于开发新合金，更好地结合汽车和其他应用的功能特性。对合金行为的详细了解将提高加工操作的可靠性，从而提高工业部门的生产率。
