| 摘要: |
| 分别采用电弧熔炼和机械合金化法制备Nd60Fe30-xZrxAl10(x=5,10,15,20)晶态和纳米非晶态合金,并利用X射线衍射仪、振动样品磁强计等对制备的晶态合金和纳米非晶态合金的结构及其磁性能进行分析,研究Fe和Zr相对含量的变化对合金相的组成及磁性能的影响。结果表明:Nd60Fe30-xZrxAl10(x=5,10,15,20)合金晶态及纳米非晶态合金均显示软磁性;对于晶态样品,随着Zr含量的增加,样品的磁化强度逐步降低;对于纳米非晶态合金,随着Zr含量的增加,合金的饱和磁化强度降低;相同成分的纳米非晶态合金的饱和磁化强度高于相应的晶态合金的饱和磁化强度。Nd60Fe20Zr10Al10混合粉末球磨100 h后达到了完全非晶化,说明Nd60Fe20Zr10Al10有较好的非晶形成能力。 |

| Abstract: |
| Crystalline and nano-amorphous Nd60Fe30-xZrxAl10 (x=5, 10, 15 and 20) alloys were prepared by arc melting and mechanical alloying, respectively.The evolution of microstructures and magnetic properties for the alloys were investigated by X-ray diffraction (XRD) and Vibrating Sample Magnetometer (VSM).The results indicate that both of crystalline and nano-amorphous Nd60Fe30-xZrxAl10 (x=5, 10, 15, 20)alloys exhibit soft magnetic properties.The saturation magnetization of the alloys decreases when Fe is substituted by Zr.The saturation magnetizations of nano-amorphous alloys are larger than those of the corresponding crystalline alloy.Nd60Fe20Zr10Al10 mixture powder is fully amorphization after ball-milling for 100 hours, indicating that Nd60Fe20Zr10Al10 exhibits high amorphous forming ability. |
