In this paper, we have developed TiZrCuPd quaternary bulk glassy alloys which seem to be favorable for future application as biomaterials because of the absence of toxic elements such as Ni, At and Be. A series of (TiZr)(50)(CuPd)(50) bulk glassy alloys exhibit high glass-forming ability (with critical diameters of 6 and 7 mm) and relatively large supercooled liquid region (Delta T-x) of over 50 K. This alloy system follows the three empirical rules for stabilization of supercooled liquid. The thermal stability of Ti40Zr10Cu36Pd14 bulk glassy alloy was also examined in correlation with the origin for the high glass-forming ability.
