| Abstract: | Molybdenum and its alloys possess a unique combination of high temperature strength and corrosion resistance, and for these reasons they have been applied in many high-tech fields. The effects of impurity elements C, N,O, doped elements and rare-earth oxide, some common elements, such as K, Si, Al, Ca, Mg, Fe, and fibre texture on the properties of ductility and brittleness are introduced in this paper. The research priority is transverse ductility and potential application in the future is also given. |
