将200 nm、1.0 μm和10μm三种粒度的高纯钨粉末，分别混合10%的1.0微米纯钛粉末，借助放电等离子烧结（SPS）炉进行高温压力烧结，制备出尺寸为φ60×10mm的W-Ti10合金样品。烧结气氛为真空，烧结压力50 MPa，烧结温度为1400℃，保温时间为10分钟。借助阿基米德排水法原理测W-Ti10合金样品的实际密度，用实际密度除以理论密度，得到烧结样品的相对致密度。从烧结样品中取样进行砂纸打磨和化学腐蚀，借助扫描电镜观察样品中孔洞特征和致密化程度；同时从折断样品的断口处，扫描电镜观察孔洞特征和分布，并拍摄SEM照片。借助Origin绘图软件，绘制出含W-Ti10合金的相对致密度分布曲线，并与纯钨样品致密度情况对比。

The w-Ti10 alloy with size of φ60×10mm was prepared by means of spark plasma sintering (SPS) furnace by mixing high purity tungsten powders of 200 nm, 1.0 μm and 10μm with 10% pure titanium powders of 1.0 μm. The sintering atmosphere was vacuum, the sintering pressure was 50 MPa, the sintering temperature was 1400℃, and the holding time was 10 minutes. The actual density of W-Ti10 alloy sample was measured by Archimedes drainage method, and the relative density of the sintered sample was obtained by dividing the actual density by the theoretical density. The samples were sampled for sandpaper grinding and chemical etching, and the pore characteristics and densification degree of the samples were observed by scanning electron microscopy. At the same time, the characteristics and distribution of holes were observed by scanning electron microscope and SEM pictures were taken. The relative density distribution curve of w-Ti10 alloy was plotted by Origin software, and compared with that of pure tungsten sample.
