Progress of Research and Applications for Mo Metal and Its Alloys

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.
