摘要:

随着航空、航天等高新技术的发展,对铝合金性能的要求也更苛刻。微合金化是提高铝合金性能的重要途径,一直是国内外主要的研究热点。稀土元素性质活泼,非常容易与铝合金基体及其溶质元素产生化合反应,能够有效改善Al-Zn-Mg-(Cu)系铝合金的微观组织结构,大幅提升其综合性能;而非稀土元素的微合金化则能弥补稀土元素微合金化的局限性,因此得到了广泛应用。本文综述了稀土元素Sc、Er、Ce和常规元素Zr、Ag、Sn、Cr、Sr等对Al-Zn-Mg-(Cu)系铝合金的微合金化作用机理,并对今后铝合金微合金化的研究发展方向提出建议。

关键词: Al-Zn-Mg-(Cu) 铝合金, 微合金化, 合金元素

Abstract:

Requirement for highperformance aluminum alloy is increasingly severe with the development of aerospace industry. Microalloying is an important approach to improve the mechanical properties of aluminum alloys, and its research has been a global focus. The property of rareearth (RE) elements are active and easy to combine with aluminum alloy matrix and solute elements, so they can effectively improve the microstructure of Al-Zn-Mg-(Cu) aluminum alloy and significantly enhance its comprehensive performance. Microalloying of non rare earth elements can compensate the negatives of that of rare earth elements, so it is widely applied. This paper reviews the function mechanism of rareearth elements Sc, Er, and Ce and regular elements Zr, Ag, Sn, Cr and Sr to the microalloying of Al-Zn-Mg-(Cu) aluminum alloys. We further present some suggestions for the development directions of microalloying of Al-Zn-Mg-(Cu) aluminum alloys.

Key words: Al-Zn-Mg-(Cu) aluminum alloy, microalloying, alloying element
