| 摘 要： | 通过Zr部分取代Al80Ni10YsCu5中的Y，获得了Al80Ni10Y5-xZrxCus（x=0、1、2、3、4）铝基非晶合金．用XRD和DSC等测试手段1分析了单辊旋淬法制备的该合金非晶条带，研究了Zr对合金体系非晶形成能力和热稳定性的影响．结果表明，x=2或x=3的合金的衍射峰较为宽化；当x从0增加到2时，合金的晶化温度增加，此后，随x的进一步增加，合金的晶化温度先降低后又有所回升．Al80Ni10Y3Zr2Cu5合金既具有相对较好的非晶形成能力，又具有较高的热稳定性．

| Abstract: | The amorphous alloys Al_(80)Ni_(10)Y_(5-x)Zr_xCu_5(x=0,1,2,3,4) were gotten by partial replacement of Y by Zr in the alloy Al_(80)Ni_(10)Y_5Cu_5.The effect of Zr on glass forming ability and thermal stability of the alloys were investigated with XRD and DSC analysis of the amorphous ribbons prepared by melt-spinning method.The results indicated that the glass forming ability of the alloy is better when x=2 or 3;with the increase of x from zero to 2,the thermal stability of the alloys increases,but it decreases with further increase of x and then increases again.The alloy Al_(80)Ni_(10)Y_3Zr_2Cu_5 exhibits both high GFA and high thermal stability. |
