    摘要:

    為了研究具有亞微米組分的鉬銅粉末燒結時的晶間反應機制，采用亞微米活化層法制備了一種具備晶間反應層的鉬銅復合材料。采用X射線衍射儀（XRD）、掃描電鏡（SEM）、能譜儀（EDS）、透射電鏡（TEM）、高分辨透射電鏡（HRTEM），對Mo-15Cu合金組織形貌、連接和結構特征進行了表征。研究了亞微米活化層對鉬銅復合材料晶間反應的影響。結果表明，添加8%（質量分數(shù)）亞微米粉，可形成厚度約0.5 μm納米活化層。Mo亞微米顆粒通過流動、擴散，改變晶間反應機制，形成了真正意義上的晶間反應層，厚度約為5 nm，實現(xiàn)了冶金結合。

    Abstract:

    In order to investigate the intergranular reaction mechanism during sintering of molybdenum-copper powders with submicron components, a Mo-15Cu composite with an intergranular reaction layer was prepared by a submicron-activated layer method. The histomorphology, connectivity and structural characteristics of Mo-15Cu alloy were characterized by X-ray diffracto-meter (XRD), scanning electron microscope (SEM), energy dispersive spectrometer (EDS), transmission electron microscope (TEM), and high-resolution transmission electron microscope (HRTEM). The effect of submicron-activated layers on the intergranular reaction of Mo-15Cu composites was investigated. The results show that the submicron-activated layer with a thickness of 0.5 μm is formed by adding 8wt% submicron powder. The submicron-sized Mo particles change the intergranular reaction mechanism through flow and diffusion, forming an intergranular reaction layer with a thickness of about 5 nm and achieving metallurgical bonding.
