摘　　要：钼合金及钼基复合材料因高熔点、较高的高温强度、适宜的密度、低热膨胀系数等优良性能已在冶金、机械、航空航天、核工业等领域得到广泛应用。钼的电子结构决定了其本征脆性,而通过合金化、第二相强化、大塑性变形等方式可以改善钼的非本征脆性,提高钼基材料高温强韧性。本文综述了钼基材料强化方式与强化型钼合金及复合材料的研究现状,分析了钼基材料高温力学性能影响因素,展望了高强钼基材料的发展方向。Molybdenum alloys and molybdenum-based composites have been widely used in metallurgy,machinery,aerospace,nuclear industry and other fields because of their excellent properties such as high melting point,high-temperature strength,suitable density and low thermal expansion coefficient.The electronic structure of molybdenum determines its intrinsic brittleness,while the non-intrinsic brittleness,high-temperature strength and toughness can be improved by alloying,second phase strengthening,large plastic deformation,etc.In this paper,the strengthening methods and research status of strengthened molybdenum alloys and their composite materials are reviewed,the factors affecting the high temperature mechanical properties of molybdenum-based materials are analyzed,and the development direction is also prospected.
