Advanced Aluminum Alloys from Rapidly Solidified Powders

Abstract

The objective of this program is to develop advanced aluminum alloys from rapidly solidified particulate that meet specific property goals (A & B). In addition, the program is to establish a metallurgical basis suitable for manufacturing scale-up and application to new weapon systems. Goal A is a 30% increase in specific modulus of elasticity relative to Al 7075-T76, without significant loss in strength, toughness, fatigue strength, or stress-corrosion resistance. Goal B is a 20% increase in specific modulus of elasticity accompanied by a 20% increase in specific strength, without significant loss in toughness, fatigue strength, or stress corrosion resistance.
