| Abstract: | Variations in microstructure, density, strength and plasticity of Al-Li-Cu alloy with Li content of 2.5% were systematically studied as Cu content changes in a range from 0 to 6 wt%. It is indicated that the strength and density increase and the plasticity decreases with the increase in copper content. The effect of copper content on the precipitation and fracture behaviors are also discussed. |
