The thermal properties, glass forming ability (GFA) and mechanical properties of a series of Ti40Zr10Cu40-xPd 10Six (x = 0, 1, 2) bulk glassy alloys were examined by differential scanning calorimetry (DSC), differential thermal analysis (DTA), X-ray diffractometry (XRD) and compression test. The bulk glassy alloys are expected to be used as biomedical materials because of the absence of toxic elements such as Ni, Al and Be. The glass-forming ability and thermal stability of the Ti-Zr-Cu-Pd alloy can be improved by a small amount of Si addition. The critical diameters for glass formation are 5 mm for both Ti40Zr 10Cu39Pd10Si1 and Ti 40Zr10Cu38Pd10Si2 alloys. A large supercooled liquid region of 65 K was obtained for the Ti 40Zr10Cu38Pd10Si2 bulk glassy alloy. The bulk glassy alloys have higher compressive strength of over 1900 MPa and lower Young's modulus below 85 GPa as compared with conventional biomedical Ti alloys.
