    摘要:

    采用液相燒結(jié)法制備出Mo-30Cu合金,利用XRD,SEM,TEM等對(duì)該合金的組織進(jìn)行分析觀察,并研究燒結(jié)溫度、相對(duì)密度對(duì)Mo-30Cu合金組織性能的影響。結(jié)果表明:該合金組織分布均勻,組織中只含有Mo、Cu兩相,在兩相之間有一Mo、Cu互溶區(qū);燒結(jié)溫度是影響Mo-30Cu性能的最重要因素,在1300 ℃燒結(jié)的合金相對(duì)密度為99.6%,熱導(dǎo)率為196 W·(m·K)-1

    Abstract:

    Mo-30Cu alloy was prepared by liquid sintering. Microstructures and composition of the alloy were analyzed with SEM, TEM and XRD, and the influence of sintering temperatures and relative density on microstructures and properties of the alloy was studied. The results indicate that the microstructure of the Mo-30Cu alloy is homogeneous, in which are only Mo phase and Cu phase for the alloy; a medium changing zone is between Mo phase and Cu phase. The sintering temperature plays the most important role on the microstructures and properties of the alloy. Relative density and thermal conductivity of Mo-30Cu alloy sintered at 1300 oC are 99.6% and 196 W·(m·K)-1, respectively
