英文摘要	In this study, (Ti0.5Ni0.5)80Cu20 metallic glass composites sample with 3mm diameter were prepared by levitation suspend melting-water cooled Cu mold process. Microstructure and thermodynamic behavior of the alloy were characterized by XRD, OM and DSC. the potention dynamic polarization curves in artificial seawater were tested by electrochemical workstation in a three-electrode system. The results showed that the as-cast microstructure of the alloy is consist of supercooled austenite phase, thermally-induced martensite phase and amorphous phase. Due to cooling rate, random dense pile of amorphous structure formed in surface of the alloy and supercooled austenite phase formed in interior. Besides, the alloy also presented excellent corrosion-resistance in artificial seawater for its higher corrosion potential(Ecorr) and polarization resistance(Rp), lower corrosion current density(Icorr) compared with Ti-6Al-4V(TC4) alloy. © 2017 Trans Tech Publications, Switzerland.
