Abstract Three ternary alloys with composition of Mg-(11-13)Gd-1Zn (mass fraction, %) have been prepared and their microstructures and mechanical properties have been also investigated. The results showed that the as cast microstructure of the three alloys consists of α-Mg matrix, (Mg, Zn)₃Gd eutectic and a 14H long--period stacking ordered (14H--LPSO) phase. With the increase of Gd content the volume fraction of the (Mg, Zn)₃Gd eutectic increases. After extrusion the (Mg, Zn)₃Gd eutectic networks are destroyed and its broken particles are arranged in strips along the direction of extrusion, and the 14H--LPSO phase is distributed between (Mg, Zn)₃Gd strips. Solid solution treatment at high temperature above 500 ℃ results in the dissolution of (Mg, Zn)₃Gd phase into the matrix and the increase of the 14H-LPSO phase. After solution treated alloys are aged at temperature of 225 ℃ (T6 treatment) the volume fraction of the 14H-LPSO phase is further increased and both β' and β₁precipitates appear in the microstructure. Aging of as extruded alloys (T5 treatment) also causes the formation of β' and β₁ precipitates but the volume fraction of the 14H--LPSO phase in the T5 treated specimens is lower than that in specimens after T6 treatment. High tensile strength combined with good ductility is obtained from the Mg--11Gd--1Zn alloy after T6 aging.

Key words: magnesium alloy Gd Zn aging long-period stacking ordered phase
