中文摘要：
采用熔渗法制取不同Fe含量的Mo-Cu合金。利用场发射扫描电子显微镜（SEM）和能谱（EDS）仪分析不同Fe含量的Mo-Cu合金的显微组织及Fe元素的分布,研究Fe含量对Mo-Cu合金的致密度、热导率、电导率、硬度以及显微组织的影响。结果表明,添加1%Fe（质量分数）使Mo-Cu合金的致密度和硬度提高,但是导电和导热性能降低。微观分析表明,添加活化元素Fe后合金显微组织更加致密,Cu呈网状分布,Mo骨架烧结颈变大,但Fe含量过多时,不利于合金性能的提高。
英文摘要：
Mo-Cu alloys with different Fe content were prepared by an infiltration method. The microstructure and distribution of Fe of the alloys were analyzed by field-emission scanning electron microscope （FESEM） and energy disperse spectroscopy （EDS）. The influence of Fe content on the density,thermal conductivity,electrical conductivity,hardness and microstructure was investigated. The results show that 1% Fe addition （mass fraction） increases the density and the hardness of the Mo-Cu alloys,but decreases thermal conductivity and electrical conductivity;meanwhile the microstructure becomes more compact,and Cu distributes in the form of mesh,and Mo skeleton sintering necks become bigger. However,too much Fe is not conducive to the improvement of properties.
