摘要	The compositional dependence of glass-forming ability (GFA) was investigated for the Ti-Ni-Si ternary alloys. Glassy ribbons varied with different thicknesses were fabricated via single-roller melt spinning. The optimized glass-forming composition was located at Ti(57)Ni(35)Si(8), with a critical thickness of about 200 mu m for complete glass formation. By characterizing the microstructure of arc-melted ingots of the Ti-Ni-Si ternary alloys, we demonstrate that the glass formation of the Ti(57)Ni(35)Si(8) alloy correlates with the (L -> Ti(2)Ni+TiNi+Ti(5)Si(3)) ternary eutectic reaction. In addition, the eutectic composition of the (L -> Ti(2)Ni +TiNi + Ti(5)Si(3)) ternary and (L -> TiNi + Ti(5)Si(3)) pseudo-binary eutectic reaction was determined to be in the vicinity of Ti(63)Ni(31)Si(6) and Ti(53)Ni(37)Si(10), with the invariant reaction temperature at 1243 and 1424 K, respectively.
