Development of High Modulus Corrosion Resistant Aluminum Alloys.

Abstract

The purpose of this research project was to develop high strength aluminum base alloys with increased modulus and corrosion resistance. In the first stage, processing parameters were established for the preparation of duplex alloys. A program of basic research has been undertaken with the overall goal of establishing quantitative processing-microstructure-mechanical behavior relationships in fully-dense Al-Zn-Mg/Mn modified alloys produced by powder metallurgy. Initial attention has been directed to Mn-Si and Mn-Cr modifications, powder processing, consolidation, mechanical property and corrosion response. Mechanical properties and microstructures have been characterized in the powder in extrusions and correlated with microstructures. Keywords: High modulus aluminum, Manganese addition, Aluminum alloy 7075, Extrusion, Corrosion testing, Microstructure correlation.
