摘　　要：综述了钼单晶、钼铼合金、钼钛锆(TZM)合金、钼硅合金、稀土钼合金、钼铜合金的研究现状与应用进展,详细介绍了稀土钼合金的研究与应用,包括稀土钼的韧化作用机理、稀土掺杂钼粉的粒度控制、稀土钼合金力学性能和热发射性能研究。由于钼及钼合金具有高温性能好、热传导率高、膨胀系数低等特性,因此在航空航天、核能工业等诸多领域得到广泛应用。今后,发展新的制备工艺,提供更高性能的材料,开辟新的应用领域成为钼及钼合金发展的关键。The research progress and applications for Mo single crystal, molybdenum-rhenium alloys, TZM alloys, molybdenum-silicon alloy, rare earth-molybdenum alloy, molybdenum-copper alloys were also summarized, especially, it of rare earth-molybdenum alloy were introduced in detail, including toughening mechanism of rare earth-molybdenum alloy, f.s.s.s size control of Mo powder with rare-earth element, the study on mechanical and thermionic properties of rare earth oxide-doped molybdenum. Molybdenum and its alloys are provided with good high temperature properties, low expansion coefficient and high thermal conductivity etc., and so its have been used in many fields such as aircraft and spacecraft, and nuclear power industry etc. For the future, it is the key to the develop new technology, enhance the properties of product, extend the applications.
