通过对粉末粒度、元素配比以及烧结三方面因素的讨论，浅析了其对钼合金顶头使用寿命的影响原因。结果表明：控制钼粉的粒度以及添加试剂的粉末状态，可有效提高钼合金的密度并细化晶粒；稀土元素添加总量控制在1.0%左右，可减少氧化物在钼基体中的富集，杜绝裂纹源的形成，提高钼顶头的寿命；采用氢气烧结的方式可得到质量稳定的钼顶头。
通過對粉末粒度、元素配比以及燒結三方麵因素的討論，淺析瞭其對鉬閤金頂頭使用壽命的影響原因。結果錶明：控製鉬粉的粒度以及添加試劑的粉末狀態，可有效提高鉬閤金的密度併細化晶粒；稀土元素添加總量控製在1.0%左右，可減少氧化物在鉬基體中的富集，杜絕裂紋源的形成，提高鉬頂頭的壽命；採用氫氣燒結的方式可得到質量穩定的鉬頂頭。

The factors that influence molybdenum anvil service life such as powder particle size,element mixture ra-tio and alloy sintering processing were analyzed in this paper. The results show that the alloy density can be effec-tively improved and the alloy grain size can be refined by controlling the particle size of molybdenum powder and the phase of addition reagent powder. The oxides eliguation in the molybdenum alloy was reduced,crack source was eliminated and service life of the molybdenum anvil can be improved when the tatal rare earth addition was con-trolled less than 1%. Molybdenum anvil quality was steady when sintering in hydrogen atmosphere.
