摘　　要：A356合金是目前应用最广的汽车轮毂用铝合金,但由于其强度不高,无法满足现代轮毂进一步轻量化的要求。而基于该合金对其成分进一步优化、改进甚至开发出新型高强铸造铝合金无疑是提高力学性能并进一步实现汽车轮毂轻量化最有效的方法之一。本文回顾了国内外在A356合金微合金化方面的研究进展,并详细阐述了合金元素对其微观组织和力学性能的作用规律,同时对现代轮毂用新型高强韧铸造铝合金的研发方向进行了展望。Nowadays,A356 alloy is the most widely used alloy for automotive wheels.However,its low mechanical properties are restricting its widespread application to modern lightweight wheels.Further optimizing A356 alloy composition or developing a new type of high-strength cast aluminum alloy for automobile wheels is one of the most effective methods for realizing the lightweight requirements of modern wheels.In this review,we briefly summarized the latest research progress of A356 alloy for automobile wheel hubs,and expounds the influence rule of alloying elements on the microstructure and mechanical properties.At the same time,the development tendency of novel cast aluminum alloys with high strength and ductility is also proposed in this paper.
