| 中文摘要 | The composition dependence of glass-forming ability was investigated for the Ti-Ni-Al ternary alloys. Glassy ribbons were fabricated via single-roller melt spinning. The optimal glass-forming composition was located at Ti(54)Ni(32)Al(14), with a critical thickness of about 90 mu m for complete glass formation. With respect to the Ti-Ni binary alloy, Al addition in the system only marginally improves the glass-forming ability. It is attributed to a small atomic size difference between Ti and Al. For the Ti(54)Ni(32)Al(14) alloy, together with the binary eutectic Ti(76)Ni(24) and hypereutectic Ti(68)Ni(32) alloys for comparison, phase selection in the arc-melted ingots was investigated. The optimal glass-forming composition, Ti(54)Ni(32)Al(14), is near the univariant eutectic groove of [L --> Ti(Al)(2)Ni + beta-Ti(Al)] in the phase diagram. It is suggested that if the primary crystallization of the Ti(2)Ni intermetallic can be suppressed, solidification of deeply undercooled melt will undergo such a eutectic reaction prior to glass formation.
