Designing Methodology Yields Cu-Containing Mg Alloys with Good Mechanical Properties and Corrosion Resistance

Abstract

A design methodology was developed in order to find combinations of alloying elements capable of randomizing/weakening the basal texture of magnesium alloys during recrystallization. Out of a list of promising alloying systems, two novel alloys were studied and relevant properties such as texture evolution and formability obtained. In addition, we verified that dilute copper additions are able to vastly improve the formability of specific magnesium alloys without a significant deterioration of their corrosion response. The simplicity of this methodology allows it to be readily available to any researcher that sees value in its results.
