【摘要】：采用電子束物理氣相沉積(EB-PVD)制備了納米鉬顆粒彌散強(qiáng)化銅基復(fù)合材料(Mo體積含量為2.5%~10.8%),對(duì)其材料微觀結(jié)構(gòu)、鉬含量和硬度、電阻率關(guān)系進(jìn)行了研究。結(jié)果表明:Cu-Mo復(fù)合材料中銅基體由柱狀晶銅組成,Mo顆粒平均直徑為2.4~8.1 nm;隨著鉬含量增加,銅基體柱狀晶寬度逐漸減小,Mo顆粒平均直徑逐漸增加,硬度、電阻率逐漸增加;EB-PVD制備的Cu-Mo復(fù)合材料主要強(qiáng)化機(jī)制為Orowan機(jī)制。
[Abstract]:Nanometer molybdenum particles dispersion strengthened copper matrix composites were prepared by electron beam physical vapor deposition (EB-PVD). The volume content of Mo was 2.5 and 10.8%. The microstructure, molybdenum content and hardness of the composites were studied. The results show that the average diameter of Mo particles in Cu matrix consists of columnar crystal copper is 2.4nm, and the average diameter of Mo particles decreases with the increase of molybdenum content, and the average diameter of Mo particles increases with the increase of molybdenum content, and the average diameter of Mo particles increases with the increase of Mo content, and the average diameter of Mo particles increases with the increase of Mo content. The main strengthening mechanism of Cu-Mo composites prepared by EB-PVD is the Orowan mechanism.
