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。采用X射线衍射仪(XRD),测试烧结样品的相分布。
After weighing, ultra-pure W and high-pure Ti/TiH2 powders were put into a V-type 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. High-temperature and high-pressure sintering tests were carried out in a vacuum hot pressing furnace, with sintering temperature of 1400℃, pressure of 25MPa and holding time of 60min. The temperature was kept at 700 ℃ for 3.5h. The phase distribution of sintered samples was measured by X-ray diffractometer (XRD).
