Abstract
Addition of Zn to Mg–Nd–La alloys resulted in an order of magnitude drop in the minimum creep rate. This remarkable improvement in creep resistance resulted from a high number density of highly refined γ″ precipitates within the α-Mg matrix coupled with preferential segregation of Zn atoms to defect/dislocation structures. These two microstructural features are expected to enhance the creep resistance by retarding dislocation motion within the α-Mg matrix.
