Development of High Modulus Corrosion Resistant Aluminum Alloys.

Abstract

A program of basic research has been undertaken with the overall goal of establishing quantitative processing-microstructure-mechanical behavior relationships in fully-dense duplex Al-Zn-Mg-Al-Mn alloys produced by powder metallurgy. Initial attention has been directed to powder processing, consolidation, mechanical property and corrosion response. Microstructures have been characterized in the powder, hot compacted billets, forgings and extrusions. Mechanical properties of primary interest were modulus, strength, impact and ductility. The goal of this highly exploratory program was to develop a duplex, aluminum alloy in which an MnAl6 aluminide dispersant phase provided for modulus/strength contributions, while the Al-Zn-Mg matrix imparted ductility and toughness.
