This study determined the independent effects of various homogenization cycles and
precipitation treatments on the elevated temperature workability and the final ambient
temperature mechanical properties of AA2024 aluminum alloy and on the T3 tensile
properties of 2014 aluminum alloy as well as T6 tensile properties of 2618 and 2618 (Curich)...
The base Al-Zn superplastic alloy was investigated at 250°C to
determine the effect of small amounts of magnesium on mechanical
properties. Six alloys of nominal composition 0.00, 0.10, 0.25,
0.50, 0.75, and 1.00 weight percent magnesium, constant 78 weight
percent zinc, and variable 21 to 22 weight percent aluminum were...
