HfV_2及ZrV_2是超导性能良好的C-15化合物(Laves相),但由于它们的脆性致今未能成为实用超导材料。我们使用旋熔法(melt spinning)使熔体淬火时抑制部分结晶,企图使C15超导体颗能均匀的弥散在柔软的非晶态基体中,有可能获得超导与机械性能良好的实用超导材料。HfV与ZrV的成分选择在共晶成分附近;Hf_(60)Zr_(40)的熔点为1500℃,Zr_(60)V_(40)的熔点为1200℃,旋熔结果获得脆性的HfV薄带柔性的ZrV薄带。我们用EM420电镜观
HfV_2 and ZrV_2 are excellent superconducting C-15 compounds (Laves phase), but due to their brittleness has not become a practical superconducting material. We use melt spinning to quench some of the melt quenching crystallization, in an attempt to make C15 superconducting particles dispersed in a soft amorphous matrix, it is possible to obtain superconducting and mechanical properties of good practical superconducting materials . The composition of HfV and ZrV is near the eutectic composition. The melting point of Hf 60 Zr 40 is 1500 ℃ and the melting point of Zr 60 V 40 is 1200 ℃. ZrV ribbon. We use EM420 electron microscopy
