摘要：

A new Mg65Cu25Gd10 alloy having significantly improved glass-forming ability (GFA) has been developed. In this article, we show that the ternary Mg65Cu25Gd10 bulk metallic glass with diameter of at least 8 mm can successfully be fabricated by a conventional Cu-mold casting method in air atmosphere. The critical cooling rate for glass formation was estimated on the order of magnitude of approximately 1 K/s. When compared with the GFA Of Mg65Cu25Y10 alloy, the significantly improved GFA Of Mg65Cu25Gd10 alloy cannot be explained by DeltaT(x) and T-rg values.
