| 摘 要： | 采用放电等离子烧结(Spark Plasma Sintering,SPS)方法成功制备得到10%(体积分数)TiNb/Zr55Cu30Al10Ni5和TiNb/Cu46Zr42Al7Y5非晶基体复合材料。压缩力学实验表明,TiNb颗粒对Zr55Cu30Al10Ni5的增韧效果明显好于对Cu46Zr42Al7Y5。究其原因是Zr55Cu30Al10Ni5的塑性转变区域的长度Rp值高于Cu46Zr42Al7Y5,这就意味着TiNb颗粒分布在Zr55Cu30Al10Ni5的塑性转变区域的几率明显高于Cu46Zr42Al7Y5基体。因此,TiNb颗粒对Zr55Cu30Al10Ni5基体的增韧效果明显要好于Cu46Zr42Al7Y5。 |

| Abstract: | TiNb/Zr55Cu30Al10Ni5 and TiNb/Cu46Zr42Al7Y5 bulk metallic glass composites were prepared by Spark Plasma Sintering (SPS). The compression results show that TiNb/Zr55Cu30Al10Ni5 composites get larger plasticity than TiNb/Cu46Zr42Al7Y5 composites. The reason is that Zr55Cu30Al10Ni5 bulk metallic glass is resistant to micro-crack. The fracture toughness test proves that KC of Zr55Cu30Al10Ni5 is higher than that of Cu46Zr42Al7Y5, so there is a larger length scale of plastic process zone Rp for Zr55Cu30Al10Ni5. |
