چکیده انگلیسی
The remarkably enhanced mechanical performance of Mg-8Gd-1Er-0.5Zr alloy with lower rare-earth content was achieved on the route of extrusion, rolling and aging processes in the present investigation. Results indicated that the ultrahigh UTS of 560â¯MPa and YTS of 518â¯MPa as well as elongation of 4.8% at ambient temperature were obtained. The β phase with size of 100-200â¯nm was precipitated during rolling in accompany with refined grains and strong basal texture, and the layer-structured precipitates with nanoscale were formed during aging. The fine β phase coordinating with strong basal texture as well as fine grain size controlled the mechanical performance of the rolled alloy, whereas the layer-structured precipitates contributed to the remarkably enhanced mechanical properties of the aged alloy.
