Abstract

Phase metastability of in-situ formed β-Zr/Ti plays a vital role on mechanical properties of Zr/Ti-based bulk metallic glass composites (β-type BMGCs). In the current study, internal friction behaviors of Ti_50.3Zr_33.9Cu_4.6Ni_2.1Be_9.1 BMGC containing metastable β-Ti and Ti_50.3Zr_27.9Cu_4.6Ni_2.1Be_9.1Mo₆ BMGC containing stable β-Ti were investigated by mechanical spectroscopy. Prior to the glass transition temperature T_g, Ti_50.3Zr_33.9Cu_4.6Ni_2.1Be_9.1 BMGC exhibits pronounced internal friction ascribed to the precipitation of ω-Ti in the metastable β-Ti phase. The current investigation not only reveals the fundamental mechanism of the internal friction process of BMGCs, but also provides an effective method to characterize the metastability of β phases in β-type BMGCs.
