Abstract The structural relaxation and glass-forming ability(GFA) of Mg-Cu-Gd-based glassy alloys and the effect of Ni addition on structural relaxation and mechanical properties were studied by thermal analysis, X-ray diffractometry (XRD) and transmission electron microscopy (TEM). The medium-range order(MRO) zones of about 1-2nm size were observed in the Mg65Cu25Gd10 glassy alloy after structural relaxation caused by annealing for 180s at 305K. Partial substitution of Cu by Ni in Mg-Cu-Gd-based alloys not only improved the mechanical properties, but also increased the stability against structural relaxation.

Key words: Mg-Cu-Ni-Gd alloys structural-relaxation mechanical properties
