摘　　要：钼及其合金以其诸多优异的性能在各个领域内受到广泛关注,但其抗蠕变性能、高温强度及抗氧化的劣化以及批量化生产手段的不足限制了大规模的工业应用。本文综述了金属钼的脆性来源,指出非本征脆性的改进及制备工艺的革新是钼合金研究和开发的重点方向。介绍了目前钼合金强韧化的主要形式,列举了典型钼合金研究开发现状,总结了钼合金的研究方向。The molybdenum alloy has received more and more attention in various industrial fields,but its extensive applications are restricted due to the degradation of its creep resistance,strength,and oxidation resistance at high temperature,and the lack of effective mass production methods.This research analyzes the brittleness source of pure molybdenum,and reveals that the improvement of extrinsic brittleness and innovation of preparation process are the key directions of research and development of molybdenum alloys.The methods applied for strengthening and toughening of molybdenum alloys are reviewed,and the research and application status of typical molybdenum alloys are listed.In addition,in consideration of the existing problems,the research direction of high temperature molybdenum alloys is summarized.
