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。用X射线衍射仪分析物相构成，鉴定显微组织中物相组成。

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. X-ray diffractometer was used to analyze the phase composition and identify the phase composition in the microstructure.
