摘要
快速凝固铝铿合金是一种低密度、高强度、高弹性模量的引人注目的新型航空航天结构材料。本文概述了快速凝固铝锂合金的特点、基本制备工艺及力学性能,着重综述了提高锂含量,减少氧化物的危害和研制高锆的铝铿合金这三个方面的最新进展,并简要介绍了应用现状和发展前景。
Rapidly solidified aluminum-lithium alloys are conspicuous aeronautic and astro- nautic structural materials with low density,high strength and high modulus of elasticity.Their characters,fundamental processes and mechanical properties were summarized.The developments of increasing Li content,decreasing the harmfulness of their oxides and researching high Zr Al-Li al- loy were recounted.The status and prospect of application of this alloy were briefly introduced.
