High Strength to Weight Aluminum - 18 Weight Percent Magnesium Alloy through Thermal Mechanical Processing.

An Aluminum-18 weight percent Magnesium alloy was prepared by casting and then warm rolling at 425C to 94 true strain. This alloy was compression tested at six strain rates from 0.00664 per minute to 0.332 per minute and at eight temperatures ranging from 25C to 425C. The most significant result is that a warm rolled Aluminum-18 weight percent Magnesium alloy can exhibit compressive strengths in excess of 95 ksi, in a material of 10 lower density than commerical high strength Aluminum alloys.
