取称量后的超高纯W及高纯Ti/TiH₂粉末，放入混合了一定比例钨球的V型混料机进行均匀混料，物料以钛箔包裹后置于石墨模具，在真空热压炉内开展高温高压烧结试验。选取烧结温度1400℃、压力25MPa、保温时间60min，并在700 ℃时保温3.5h。通过微区成分分析的场发射电子探针显微分析仪（EPMA）观察合金的微观组织，面扫描分析W-Ti元素间的扩散。其中EPMA加速电压30KV，分辨率3nm，放大倍数1000-3000×。

After weighing, ultra-pure W and high-pure Ti/TiH2 powders were put into a V-shaped mixer mixed with a certain proportion of tungsten spheres for uniform mixing. The materials were wrapped with titanium foil and placed in a graphite mold to carry out high-temperature and high-pressure sintering test in a vacuum hot pressing furnace. Sintering temperature 1400℃, pressure 25MPa, holding time 60min, and holding time 3.5h at 700 ℃ were selected. The microstructure of the alloy was observed by field emission electron probe microanalyzer (EPMA), and the diffusion between W-Ti elements was analyzed by plane scanning. The EPMA acceleration voltage is 30KV, the resolution is 3nm, and the magnification is 1000-3000×.
