以含Ni钨烧结体为研究对象，测试Ni添加后钨烧结体组织特性的变化。SEM采集方案：将将样品破坏露出新鲜断面，放入扫描电镜中，加速电压为10-20kV。EBSD采集方案：对样品表面进行机械研磨和抛光，然后在25%高氯酸和75％的酒精混合溶液中，进行电解抛光。通过EDAX配置的电子背散射衍射（EBSD）进行测量，扫描区域为900μm×900μm，步长为2μm。

Taking the Ni-containing tungsten sintered body as the research object, the changes in the microstructure characteristics of the tungsten sintered body after Ni addition were tested. SEM collection scheme: The sample is destroyed to expose a fresh section, and placed in a scanning electron microscope, and the acceleration voltage is 10-20kV. EBSD collection scheme: mechanically grinding and polishing the surface of the sample, and then electropolishing in a 25% perchloric acid and 75% alcohol mixed solution. Measured by electron backscatter diffraction (EBSD) configured by EDAX, the scanning area is 900μm×900μm, and the step length is 2μm.
