| Abstract | Glass-forming ability (GFA) of Ti-Ni-Sn ternary alloys was investigated. Applying recent models based oil atomic size ratio and efficient packing, the composition favoring the glass formation is predicted. Our experiments indicate that the optimized glass-forming composition is located at Ti56Ni38Sn6, with the critical thickness of complete glass formation approaching 100 mu m for the melt-spun ribbons. The Ti56Ni38Sn6 metallic glass exhibits a sizable supercooled liquid region (Delta T-x) of about 35 K and a reduced glass transition temperature (T-rg) of 0.52. We demonstrate that the glass formation of the Ti56Ni38Sn6 alloy correlates with the (L -> TiNi + Ti3Sn) Pseudo binary eutectic reaction in Ti-Ni-Sn ternary system, which has an invariant temperature and composition at similar to 1370 K and similar to Ti58Ni34Sn8, respectively. With respect to Sn-free Ti-Ni binary alloys, the GFA is enhanced for the Ti-Ni-Sn ternary alloys, but the improvement is limited possibly due to changes in the crystalline phases competing with glass formation.
