Sintering Mechanism of Mo-Cu Composites

Han Shengli,Song Yueqing*,Cui Shun,Xia Yang(Powder Metallurgy and Special Materials Research Department,General Research Institute for Non-Ferrous Metals,Beijing 100088,China)  
Mo-Cu composites with the higher thermal and electronic conductivity and lower thermal expansion coefficient is a new type material being investigated widely.Solid phase sintering and liquid phase sintering of Mo-Cu composites were investigated and sintering mechanism of Mo-Cu composites was analysed.The results showed that microstructure of Mo-Cu composites by solid phase sintering was worse,there were a large amount of holes in body,and densification was lower while liquid phase sintering of Mo-Cu composites might be divioled into three stages including rearrangement,solution-reprecipitation and solid phase sintering of Mo.
