Abstract

The thermal properties, glass forming ability (GFA) and mechanical properties of a series of Ti40Zr10Cu40-xPd10+x (x = 0, 2, 4, 6, 8, 10) bulk glassy alloys were examined by differential scanning calorimetry (DSC), differential thermal analysis (DTA), X-ray diffractometry (XRD) and compressive test. The series of 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 Ti40Zr10Cu36Pd14 alloy exhibits the highest GFA, resulting in a maximum diameter of 6 mm, and high thermal stability with a supercooled liquid region (ΔTx) of 49 K. The bulk glassy alloy has higher specific strength of 2.7 × 105 Nm/kg and lower Young's modulus of 82 GPa than those of conventional biomedical Ti alloys. These are favorable for application to biomaterials.
