... strengths than other aluminum-lithium alloys ( Table 2 ). At lower copper/magnesium ratios, the S ′ phase is favored, and lower strengths are achieved (e.g., alloys 8090 and 2091). In the absence of copper, the δ′ phase becomes predominant, resulting in even lower strength (e.g., Soviet alloy 01420...

... (such as 8090 and 2091) with higher lithium contents to maximize density reduction. The quaternary alloys based on Al-Li-Cu-Mg (such as 8090) are the most common, due to a good combination of strength, ductility, and toughness. The Al-Li-Cu-Mg alloys are strengthened by three types of precipitates: δ′ (Al 3 Li...
