The thermoplastic deformation behavior of a Zr47.3Cu 32Al8Ag8Ta4Si0.7-based bulk metallic glass composite (BMGC) is studied using thermal mechanical analyzer (TMA) and high temperature compression test in the supercooled liquid (SCL) region. The deformation behavior of the Zr47.3Cu 32Al8Ag8Ta4Si0.7-based BMGC rod is investigated using TMA under compression at different strain rates (5 × 10-2 to 5 × 10-1 s-1) and at different temperatures above the onset temperature of viscous-flow (∼740 to 764 K) in the SCL region. It is observed that; at a constant strain rate of 5 × 10-2 s-1; the flow stress decreases with increasing temperature and reaches a relatively low value about 76 MPa at 764 K. In parallel; the value of flow stress increases with increasing strain rate at the same testing temperature. A satisfactory thermoplastic forming ability of the Zr47.3Cu32Al8Ag8Ta 4Si0.7-based BMGC in the SCL region is demonstrated by imprinting the hologram pattern. © 2012 Elsevier B.V.
