摘要
铝锂合金经过长期的发展,因其优异的力学性能和低密度等优势被广泛应用于航空航天领域。本文章主要对铝锂合金的发展历史、研究现状及应用实例进行详细的阐述,并对未来全球铝锂合金用量进行估计。尽管存在成品率低、生产成本居高不下等问题,铝锂合金在航空航天及其他领域具有较大的发展潜力。
Aluminum-Lithium (Al-Li) alloy has been applied in aerospace industry widely for a long term development due to its excellent mechanical properties and low density advantages. The development history, research status and application examples of Al-Li alloy were described in this paper, and global demand for the alloy in future was estimated. In spite of the problems of low yield and high production cost, Al-Li alloys have great potential in aerospace and other sectors.
