Fabrication and Properties of Cu/MgB2 Composites by Vacuum Sintering

摘要：

　　Cu/MgB2 composites with different content of MgB2 (10,20,30 vol.%) were fabricated by vacuum sintering of copper and MgB2 powders.The effects of MgB2 content and sintering process on the properties of Cu/MgB2 composites including the microstructures,relative density,electrical conductivity and hardness were then investigated.The results showed that the distribution uniformity of MgB2 on copper matrix decreased obviously with the increase of MgB2 content,the hardness of Cu/MgB2 composites increased and the relative density decreased slightly though the electrical conductivity decreased greatly.The relative density and hardness of Cu/MgB2 composites increased after the repressing-resintering process,the electrical conductivity was also improved slightly.
