Part I discusses the development of an aluminum-magnesium-silicon alloy that may combine strength, extrudability, favorable corrosion resistance with low cost and scrap compatibility. The first part of the study determined the effects of small composition, heat treatment and mechanical processing changes on the ambient temperature tensile properties of the alloy....
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...
