摘要


随着新能源电力系统和电气装备向轻量化、低成本方向发展，开发高强度和高导电性的Al-Mg-Si系铝合金材料已成为实现“以铝代铜”的重要研究方向。然而，合金元素固溶、析出强化及形变缺陷对电子输运的不利影响，使强度与导电性能之间长期存在协同优化难题。近年来，围绕合金化设计与形变热处理协同调控的研究不断深入，通过对合金成分、析出相特征及缺陷结构的精细调控，在一定程度上缓解了强度与电导率之间的制约关系。本文综述了Al-Mg-Si系导电铝合金在合金化设计与形变热处理方面的研究进展，重点总结其对微观组织演化及力学-导电性能协同调控的作用机制。此外，本文也对该类导电铝合金的未来发展方向进行展望，为新一代高性能导电铝合金的设计与工程应用提供理论参考。
