中文摘要：

非结晶的 Cu-Ti-Ni 合金的带子被旋转方法的 melt 准备。这些带子的非结晶的结构被 X 光检查 diffractametry 和传播电子显微镜学证实。Cu-Ti-basedalloys 的形成眼镜的能力上的 Ni 的效果被微分扫描热量测定(DSC ) 学习。这被发现过冷的液体区域，三角洲 T_x 价值在 x = 显示出 61 deg C 的最大的价值 10 在 theCu_(50 )Ti_(50x ) Ni_x。(x = 0， 5， 10， 15 莫耳分率，百分比) 系统。并且减少的玻璃转化温度， T_(rg ) 比 0.45 小。形成 Cu-Ti 合金的能力(GFA ) 的玻璃没被 Ni 增加有效地支持。

英文摘要：

Ribbons of amorphous Cu-Ti-Ni alloys were prepared by the melt spinning method. The amorphous structure of these ribbons was confirmed by X-ray diffractametry and transmission electron microscopy. The effect of Ni on the glass-forming ability of Cu-Ti-based alloys was studied by differential scanning calorimetry（DSC）. It is found that the supercooled liquid region, △Tx value shows the maximum value of 61℃ at x=10 in the Cu50Ti50-xNix （x= 5, 10, 15 mole fraction, %） system. And the reduced glass transition temperature, Frg, is smaller than 0.45. The glass forming ability（GFA） of Cu-Ti alloy is not effectively promoted by Ni addition.
