Abstract
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 57Ni 35Si 8, with a critical thickness of about 200 μm 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 57Ni 35Si 8 alloy correlates with the ( L → Ti 2Ni + TiNi + Ti 5Si 3) ternary eutectic reaction. In addition, the eutectic composition of the ( L → Ti 2Ni + TiNi + Ti 5Si 3) ternary and ( L → TiNi + Ti 5Si 3) pseudo-binary eutectic reaction was determined to be in the vicinity of Ti 63Ni 31Si 6 and Ti 53Ni 37Si 10, with the invariant reaction temperature at 1243 and 1424 K, respectively.
