| 中文摘要 | 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 Ti(56)Ni(38)Sn(6), with the critical thickness of complete glass formation approaching 100 mu m for the melt-spun ribbons. The Ti(56)Ni(38)Sn(6) 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 Ti(56)Ni(38)Sn(6) alloy correlates with the (L -> TiNi + Ti(3)Sn) 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 Ti(58)Ni(34)Sn(8), 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.
