Ti-Zr-Cu-Pd-Sn bulk glassy alloys have been synthesized by copper mold casting. The thermal properties, glass-forming ability (GFA) and mechanical properties were examined by differential scanning calorimetry (DSC), differential thermal analysis (DTA), X-ray diffractometry (XRD) and compression test. The series of bulk glassy alloys is expected to be used as biomedical materials because of the absence of toxic elements such as Ni, Al and Be. The 10 mrn rods with full glassy structure can be obtained for the Ti40Zr10Cu34Pd14Sn2 and Ti40Zr10Cu32Pd14Sn4 alloys by copper mold casting. The Ti40Zr10Cu36-xPd14Snx(x = 0, 2, 4, 6) glassy alloys have a large supercooled liquid region of over 50 K. The Ti40Zr10Cu34Pd14Sn2 bulk glassy alloy exhibits good plasticity of 3.5% during compressive applied load at ambient temperature in conjunction with distinct yield strain of 2.2% and high fracture strength of about 2050 MPa.
