摘要

利用常规的金属型喷铸法制备出不同直径的Mg65Cu25-xNixTb10（x=0～10.0）非晶合金。利用X射线衍射、差热分析、准静态压缩试验和扫描电镜

分析了添加Ni元素对Mg-Cu-Tb非晶合金形成能力及力学性能的影响。结果表明

Ni的加入降低了Mg-Cu-Tb-Ni合金的非晶形成能力与热稳定性

但适量的Ni可以显著提高合金的断裂强度

其中Mg65Cu20Ni5Tb10的断裂强度达到了943MPa

远高于原始的Mg65Cu25Tb10三元非晶合金。

Abstract

Amorphous Mg65Cu25-xNixTb10（x makes 0～10）rods with different diameters were prepared by conventional Cu mold casting method.Effects of Ni addition on the glass forming ability and mechanical properties of Mg-Cu-Tb amorphous alloy were analyzed by means of XRD（X-ray diffraction）

DSC（differential scanning calorimetry）

quasistatic compression testing and SEM（scanning electron microscope）.It is found that although it can decrease the glass forming ability and thermal stability of the alloy

appropriate Ni addition can greatly improve the fracture strength of Mg-Cu-Tb-Ni amorphous alloys

in which fracture strength of Mg65Cu20Ni5Tb10 can reach 943MPa

much higher than Mg65Cu25Tb10 alloy.
