摘要

铝合金材料广泛应用于航空航天等领域，但其高温强度相对于钢铁材料还有一定的差距。通过添加过渡族金属和稀土金属元素可有效控制铝合金高温条件下的析出强化相（Al3X），从而提升其高温力学性能。概述了微合金元素对铝合金高温强化影响的国内外研究进展，并结合第一性原理计算阐述了 Al3X 强化相热力学参数及其性能方面研究的最新进展。

Abstract

Al alloys are widely used in aerospace industries

but their high-temperature strength still cannot match with steels. Addition of transition metals and rare earth elements can effectively control the precipitation strengthening phases (Al3X) in Al alloys under high temperature conditions

and therefore their high-temperature mechanical properties can be improved significantly. This paper summarizes the current research progresses of the influence of microalloying elements on the high temperature precipitation strengthening of Al alloys. Combined with first-principles calculation

the latest developments in the thermodynamic parameters and properties of Al3X strengthening phase are described.
