is characteristic of amorphous structure. It is in agreement with the previous research[7] that fully glassy alloy bulk rods with 8 mm in diameter can be fabricated. With increasing Al content, the maximal diameter for fully glassy bulk rod gradually decreases. For x=1 and x=3, the diameter of these fully glassy rods is less than 7 mm and 6 mm, respectively. While for x=5, the maximal size of fully glassy alloy......
