Formation of Ti-based bulk metallic glasses was investigated in (Ti,Zr)–(Cu,Ni) pseudobinary system. It was found that glass-forming ability was significantly improved by the addition of Zr and Ni to the Ti–Cu binary alloys. For Ti50Zr5Cu40Ni5, Ti45Zr5Cu45Ni5, Ti42.5Zr10Cu42.5Ni5 and Ti42.5Zr7.5Cu45Ni5 alloys, glassy alloy rods with diameters of 2 and 3 mm can be obtained by a copper mold casting method. The glassy alloys exhibit high compressive fracture strength of about 2 GPa, and the bulk glassy Ti45Zr5Cu45Ni5 alloy shows distinct plastic strain of 0.018.
