摘　　要：钼合金具有更加稳定的显微组织、韧-脆转变温度低、高温性能稳定等优点得到了国内外学者的广泛关注。概述了氧化物对钼合金的强化方法和机理,通过第二相的掺杂方式、粒子尺度、氧化物的种类和含量对钼合金的再结晶温度和塑性、室温和高温力学性能等影响进行归纳总结,并对理论研究和工艺优化的结合产生的新型氧化物钼合金的发展进行了展望。The molybdenum alloy has more stable micro-structure, low toughness-brittle transition temperature,and the high temperature performance stability have been widely concerned by scholars at home and abroad. The improvement method and mechanism of oxide on molybdenum alloy are summarized. By The effects of doping of the second phase on the particle scale, the oxide and the content of the re-crystallization temperature and plasticity on the room temperature and high temperature mechanical properties of molybdenum alloy are concluded. The development of a new molybdenum oxide alloy produced by the combination of theoretical research and process optimization is prospected.
