The experimental results show that microwave sintering promotes the densification of green compacts with higher heating rate and reduced sintering cycle. The sintered relative density of 99.8% can be achieved during microwave processing under appropriate conditions. In addition, microwave sintering improves the uniformity and homogenization of W grain size, and yet leads to growth of W grain. Fe sintering aid degrades the microstructure uniformity and further coarsens W grains. The present investigation demonstrates the feasibility of applying microwave sintering technique to consolidate W-Cu composites and its promising outlook in reducing production cycle and cost.

结果表明：微波烧结升温速度快，周期短，能促进W-Cu材料的致密化；在适当条件下，微波烧结能获得相对密度达99.8%的W-Cu样品；微波烧结能改善W-Cu样品中两相分布的均匀性和W晶粒尺寸的一致性，但引起W晶粒的快速长大；Fe烧结助剂导致W-Cu材料显微组织均匀性变差，并引起晶粒进一步粗化；微波烧结技术能够应用于W-Cu材料的制备，在缩短生产周期、降低生产成本方面具有潜在优势。

The main reasons are: the reaction+=Fe+CO also occur during molten iron drop passing final slag, the slag has lowlevel of FeO ,but it still has strong decarburizing capability. In addition, during molten irondrop passing final slag, the dynamic conditions of decarburizing reaction is well, it makethe carbon content of liquid iron reduce.
