将200 nm、1.0 μm和10 μm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。从烧结样品的心部进行电火花线切割取样，借助金相抛光机进行金相制样和化学腐蚀。借助扫描电镜观察样品的晶粒形貌，并拍摄SEM照片；同时，从折断样品的断口上，进行晶粒形貌的SEM拍照。利用图像处理软件Image J 统计出SEM照片中的平均晶粒尺寸，并与烧结纯钨样品对比。借助Origin绘图软件，绘制出含Ti钨合金和纯钨烧结样品的平均晶粒尺寸分布曲线。

The high-purity tungsten powder with three particle sizes of 200 nm, 1.0 μm and 10 μm was mixed with 10% 1.0 micron pure titanium powder respectively, and the spark plasma sintering (SPS) furnace was used for high-temperature pressure sintering to prepare a size of φ60×10mm. W-Ti10 alloy sample. The sintering atmosphere is vacuum, the sintering pressure is 50 MPa, the sintering temperature is 1400°C, and the holding time is 10 minutes. Wire EDM samples were taken from the core of the sintered sample, and metallographic sample preparation and chemical corrosion were performed with the help of a metallographic polishing machine. Observe the crystal grain morphology of the sample with the help of scanning electron microscope, and take SEM pictures; at the same time, take SEM photographs of the crystal grain morphology from the fracture of the broken sample. The image processing software Image J was used to calculate the average grain size in the SEM photos and compared with the sintered pure tungsten sample. With the aid of Origin drawing software, the average grain size distribution curve of Ti-containing tungsten alloy and pure tungsten sintered sample is drawn.
