摘要

A new Mg-Sn-Zn based alloy modified with a small amount of Ag exhibits a significantly higher aging peak than that of the base alloy and at a considerably shorter aging time. The enhanced aging response of the Ag-modified alloy is ascribed to the precipitation of densely distributed MgZn_2 needles and Mg_2Sn plates stimulated by the Ag. A wide and low plateau behind the hardness peak could be associated with rod-shaped precipitates of the orthorhom-bic Mg_(54)Ag_(17) phase, aligned with the hexagonal axis of the Mg matrix.
