摘　　要：添加合金元素来提高锆合金的力学性能和耐腐蚀性能,近年来受到研究学者的广泛关注。概述了加钼锆合金的国内外研究现状和发展趋势,着重介绍了添加钼元素对锆合金力学性能、耐腐蚀性能、微观组织、形变织构、第二相等方面的影响。在锆-铌合金中添加适量的钼,再通过适当的热机械处理,可以得到高强度、耐腐蚀、晶粒细小的锆合金。In order to improve the mechanical property and corrosion resistance, adding alloy elements to Zr-based alloys receives extensive concern of researchers. The current researches of domestic and overseas and prospect for molybdenum addition zirconium alloys are reviewed, and the effect of Mo on the mechanical property, corrosion re- sistance, microstructure, deformation texture and second phase in Zr-based alloys is introduced. Adding plenty of Mo in Zr-Nb alloys as well as proper heat mechanical treatment can get high strength, high corrosion resistance and fine grains zirconium alloys.
