| 摘 要： | 利用X射线衍射(XRD)和差示扫描量热分析(DSC)研究了添加钇对Zr55 Cu30Ni5Al10Y(=0,1,2,3,4)非晶合金体系玻璃形成能力的影响。用铜模铸造获得的Zr55 Cu30Ni5Al10Y(=0,1,2,3,4)块体非晶合金的临界尺寸从直径6 mm增加到20 mm。分析认为,微量钇的添加可以与合金中的残留氧形成氧化物,降低氧对合金形成非晶态结构的负面效应。因此添加适量的稀土元素钇有利于提高Zr55 Cu30Ni5Al10Y非晶合金体系的玻璃形成能力。

| Abstract: | The effect of yttrium addition on the glass-forming ability(GFA) of ZrCu30Ni5Al10Y(0,1,2,3,4) alloys was investigated by using X-ray diffraction(XRD) and differential scanning calorimetry(DSC).The critical diameter of glassy rods increases from 6 mm for the Zr55Cu30Ni5Al10 alloy to 20 mm for the Zr53Cu30Ni5Al10Y2 alloy when prepared using copper mould casting.The addition of yttrium turns out to be effective in depressing the harmful effects of oxygen in the melt by the preferential formation of yttrium oxi... |
