  Influence of copper content on the property of Cu–W alloy prepared by microwave vacuum infiltration sintering

  摘要：

  Cu-W alloy was prepared by utilizing microwave vacuum infiltration sintering furnace to assess the influence of different proportions of copper on the structure of Cu-W alloy. The microstructures of alloy and infiltration characteristics of Cu-W alloy were characterized using metallographic microscopy and scanning electron microscopy, while XRD was utilized to identify the structure changes. The pore distribution was also assessed. Experimental results showed that Cu-W alloy could be quickly prepared under vacuum conditions through microwave infiltration sintering with the main phase of alloy being Cu0.4W0.6 (PDF:50-1451) indicating stronger combination of tungsten and copper.

  In this study, we fabricated a new type of Mo–W–Cu alloys by microwave sintering at a low temperature (1000 °C) in a short time (5 min) and characterized the phases, microstructures, and properties of the alloys. Through calculating the skin depth, it was proved that the microwave field enabled complete penetration of radiation to Mo, W, and Cu particles, thus effectively promoting the diffusion and

  在这项研究中，我们通过在低温 (1000 °C) 和短时间 (5 分钟) 下微波烧结制备了一种新型 Mo-W-Cu 合金，并表征了合金的相、微观结构和性能。通过趋肤深度的计算，证明微波场能够使辐射完全穿透Mo、W、Cu粒子，从而有效地促进Mo、W、Cu之间的扩散和固溶。XRD和TEM结果表明，Mo-W-Cu合金除Mo、W、Cu相外还含有三种新相，即Mo-W有序相、Mo-Cu固溶体和Cu 0.4 W 0.6金属间化合物。还发现Mo-W-Cu合金比Mo-Cu合金表现出更好的致密化和综合性能。烧结颈的数量和尺寸随 W 含量从 10 到 50 wt% 变化，其中在 30 wt% W 下获得最佳微观结构和性能。该研究可为进一步研究微波致密化和性能提供有用的指导烧结 Mo-W-Cu 合金。

  The CuW80 alloy was prepared by the method of microwave vacuum sintering. The effects of temperatures on the performance of CuW80 alloy was assessed based on the relative density and hardness. The micro structure of alloy was characterized using scanning electron microscopy, while XRD was utilized to identify the structure changes. Experimental results indicate CuW80 alloy with excellent performance under vacuum conditions prepared by microwave sintering. Density was found to increase with increase in sintering temperature linearly until 1200 C, while the rate of increase was found to reduce at higher temperatures, reaching an asymptote. The maximum relative density of the alloy was estimated to be 97.95% at 1300 C. At a sintering temperature of 1200 C, CuW80 alloy was more uniform with the main phase of alloy being Cu0.4W0.6 (PDF: 50-1451) and maximum hardness being 222 HBS. (C) 2014 Elsevier B. V.

  Cu-W alloy films were prepared by magnetron sputtering. Their microstructure, hardness, elastic modulus and plastic deformation were investigated by various technologies. The results show that Cu-W amorphous alloy films are formed in the composition range from Cu36W64 to Cu75W25, and out of this range solid solutions are formed. Both the hardness and elastic modulus of Cu-W amorphous alloy films are lower than their rule-of-mixture values. The load-displacement curves of Cu-W amorphous alloys with lower Cu content exhibit obvious serrated flow at lower strain rate. Serrations are suppressed at higher strain rate and higher Cu content. For all Cu-W amorphous alloy films, shear bands are observed and their number and density increase with increasing Cu content. indicating that the details of the plastic deformation of Cu-W amorphous alloys arc material-related.
