摘要

利用电磁模拟微重力装置熔炼高锂含量铝锂合金。试验结果表明:Li的质量分数为5%

0%时不产生偏析;合金密度达到了超轻合金的密度范围。通过改进坩埚结构、加热方法、热处理工艺等措施

合金的性能接近已实际应用的8090合金。

Abstract

Smelting of Al-Li alloy containing high Li content with vacuum micro-gravity apparatus based on electromagnetic analogue has been conducted. The results verify that segregation in the Al-Li alloy containing 5%

0% Li can not be observed

and the density of the Al-Li alloy is located in the density range of super-lighter alloy. The properties of the Al-Li alloy containing 5%

0% Li can approach towards practical application by improving crucible structure

heating ways and heat treatment method.
