Abstract

The role of uniaxial stress on the precipitation behavior in a Mg-2.6wt pct Nd alloy has been examined by comparing creep-tested and isothermally aged samples using transmission electron microscopy. Both types of samples exhibited precipitation of the β′(orthorhombic) and β₁(fcc) phases. During creep testing, dynamically formed β₁ precipitates are aligned along favorable slip directions within the α-Mg matrix, presumably influencing the creep response of the Mg-Nd alloy.
