Abstract
5A90 aluminum lithium molten alloy were treated using vacuum refining technology, the effect of different degree of vacuum and treatment time on the refined efficiency was studied,and the refining process parameter was determined. The result showed that the hydrogen gasses/impurity in the melt was removed largely under the optimum process condition, which is vacuum degree of 1000 Pa, treatment time of 5 min, while the alloying elements were retained effectively.
