In order to clarify intrinsic features of bulk glassy alloys, the structural control is the most significant factor. However, it is difficult to obtain a single glassy phase by conventional casting methods. Crystalline inclusions in Zr-based bulk glassy alloy are often seen on the fracture surface. Crystalline inclusions are easily formed in molten alloy state by inhomogeneous nucleation or impurities i.e. oxygen, magnesium dichloride and so on. In Zr55Cu30Ni5Al10 bulk glassy alloy, most of the crystalline inclusions are probably considered as τ3 type intermetallic compound with typical composition of Zr51Cu28Al21. The morphology of the crystalline inclusions is changed by the quantity of absorbed oxygen impurities in bulk glassy alloy.
