An Investigation of the Workability of A1-8.5% Mg Alloys

Abstract

Aluminum-magnesium alloys containing greater than 5 wt% magnesium are high strength, lightweight alloys which show potential to be utilized by the Army in armor applications. A problem encountered thus far with these high strength alloys is some difficulty in achieving necessary cold work levels to provide the alloys with optimum mechanical properties. This report details the results of an investigation of the hot and cold workability of three Al-8.5 wt% Mg alloys with variations in Mn and Cr additions. Keywords: Aluminum alloys; Lightweight alloys; High strength alloys; Rolling(metallurgy); Microstructure.
