AbstractCritical cooling rate R-c for a series of Al-based glass formers, as well as cooling rate T' for copper-mold casting Al-based bulk metallic glass (BMG) samples, have been calculated. It is found that the glass forming ability (GFA) is reflected by the change of R-c value, and Al86Ni6Y4.5Co2La1.5 alloy, the best glass former in Al-based systems, holds the lowest R-c of about 3.01 x 10(3) K/s. The T' for the rod sample is determined by casting diameter D. When synthesizing Al-based BMGs, with the D increases from 1 mm to 3 mm, the value of T' decreases from 7.48 x 10(3) K/s to 0.83 x 10(3) K/s. Based on these calculations, the critical casting diameter D-c for a certain Al-rich multi-composition could be predicted. Further, for the composition Al86Ni6Y4.5Co2La1.5, bulk glassy sample with D-c up to 1.5 mm has been obtained, confirming the theoretical prediction. (C) 2015 Elsevier Ltd. All rights reserved.
