Development of Advanced Aluminum Alloys from Rapidly Solidified Powders for Aerospace Structural Applications

Abstract

Advanced aluminum alloys are being developed that will provide majors payoffs in terms of weight savings for new aerospace structures. The two property goals are: (1) a 30-percent increase in modulus of elasticity-to- density ratio, and (2) a 20-percent increase in modulus of elasticity-to-density ratio plus a 20-percent increase in strength-to-density ratio, when compared to Al 7075-T76 and without a significant loss in other properties important for structural applications. The program is organized into three phases: 1 - a fundamental alloy and process development study; 2 - scale-up of two best alloys and evaluation of mill product forms.
