| Abstract Scope |
The Al-Li alloy is light and has high specific strength and specific modulus, and is widely used in the aerospace field. Since Al-Li alloy can be applied not only to the aerospace field but also to the automobile industry and defense industry that require alloys with high specific strength, many studies are being conducted to improve the properties.
In this study, Al-2Li-1Ce-xMg (x=0, 2, 4 and 6wt.%) alloy was gravity casted, the cast billet was hot-extruded with a rod at an extrusion ratio of 37:1, and the extruded alloy was 1.7mm thick. After processing, a rolled material of 0.65 mm was manufactured through multi-stage rolling.
XRD, FE-SEM, XRD, and EBSD were observed to analyze each alloy, and a tensile test was performed to analyze mechanical properties.
