Abstract	Adopting the "3D pinpointing approach", compositional dependence of glass-forming ability (GFA) for Ti--(Cu(1-x)Ni(x))-Sn (0.20 <= x <= 0.30, atomic fraction) quaternary alloys was systematically investigated. The alloy with the optimized GFA is located at Ti(38)Cu(37.8)Ni(16.2)Sn(8). Its Critical diameter for metallic glass formation is near 1.0 mm for the rods fabricated using Cu mold casting. This metallic glass exhibits the supercooled liquid region Delta T(x) of 56 K and the reduced glass transition temperature T(rg) of 0.57. By characterizing the microstructure of the arc-melted Ti(38)Cu(37.8)Ni(16.2)Sn(8) alloy, it is indicated that solidification of the alloy melt undergoes a pseudo-binary entectic reaction of L -> Ti(5)Sn(3)Cu + TiCuNi.
