摘　　要：研究了细颗粒钼粉的低温连续烧结工艺可行性,所制备钼坯的品质、压力加工性能及轧制成0.5 mm厚钼薄板的力学性能。研究结果表明:针对费氏粒度小于2.0μm的钼粉,利用低温连续烧结工艺可实现钼坯的烧结进程,钼坯烧结密度高、晶粒细小均匀,轧制获得的0.5 mm厚钼薄板的力学性能与对比样品相当。The practicability of fine molybdenum powder low-temperature and successive sintering process and the qualities of molybdenum billets and mechanical properties of 0. 5 mm thickness molybdenum sheet rolled by the bil-lets were studied in this paper. The results show that molybdenum sintering proceeding can be achieved by the low- temperature and successive sintering process when the molybdenum powder size lower than 2.0 μm. The density of the sintered molybdenum billets is high, the grain size is fine and uniform. The mechanical properties of 0. 5 mm thickness molybdenum sheet rolled by the billets is close to the contrast sample.
