摘要
The Al-Li powder was prepared by argon atomization.The compact Al-Li powder was canned into an aluminum container and degassed in vacuum and extruded into a bar at 400℃.The effect of extrusion ratio on the metallurgical consolidation of the powder has been studied,and the relationship of process- microstructure-property and the mechanism of age strengthening in the alloy were discussed also.
