摘　　要：钼金属作为一种难熔金属由于其良好的高温强度、抗蠕变性能、导热性能、耐蚀性能和低热膨胀系数等特性,广泛应用于航空航天、电子、新能源、半导体照明、医疗器械等重要工业领域。为了改善钼及钼合金的强度及韧性,人们通常在钼金属中加入少量金属氧化物,通过氧化物颗粒作为硬质点颗粒弥散分布在钼合金基体中,从而达到强化钼合金的作用。目前已开发出的钼合金有TZM、TZC、Mo-La_(2)O_(3)合金、Mo-Al_(2)O_(3)合金、Mo-ZrO_(2)合金等。本文综述了近年来国内外学者基于金属氧化物增强钼合金组织性能方面的研究,分析了不同金属氧化物对钼合金的粉末状态、显微硬度、相对密度、微观结构以及综合力学性能等方面的影响,并在现有研究基础上对未来金属氧化物增强钼合金性能方向发展提出了展望。Molybdenum metal,as a refractory metal,is widely used in aerospace,electronics,new energy,semiconductor lighting,medical equipment and other important industrial fields due to its good high temperature strength,creep resistance,thermal conductivity,corrosion resistance and low thermal expansion coefficient.In order to improve the strength and toughness of molybdenum and molybdenum alloys,a small amount of metal oxides is usually added to the molybdenum metal,and the oxide particles are dispersed in the molybdenum alloy matrix as hard particles,so as to strengthen the molybdenum alloy.At present,the developed molybdenum alloys include TZM,TZC,Mo-La_(2)O_(3),Mo-Al_(2)O_(3) and Mo-ZrO_(2) alloys,etc.In this paper,the microstructure and properties of molybdenum alloys reinforced by metal oxides are studied in recent years.The effects of different metal oxides on the powder state,microhardness,relative density,microstructure and comprehensive mechanical properties of molybdenum alloys are analyzed.Based on the existing research,the development direction of metal oxide reinforcedmolybdenum alloy in the future is prospected.
