Abstract

There have been many alloy systems for the Mg based bulk metallic glasses (BMGs), with the previous optimum composition being Mg₆₅Cu ₂₅Y₁₀. In this study, new optimum alloy designs are made based on the theoretical model involving the electron per atom e/a-related criterion and the recent model of optimum composition extension from the binary eutectic-pair criterion. Both models suggest that the optimum Mg based BMGs might possess a composition with a lower amount of Mg element. It follows that a series of Mg based BMGs with 50-65 at% Mg and 10-25 at% rare earth element are prepared. The glass forming ability, thermal characteristics, and mechanical performance are examined and discussed. © 2007 The Japan Institute of Metals.
