Abstract
2.0wt.% MoSi2/rare earth oxide doped molybdenum alloys were prepared by powder metallurgy processing followed by hot rolling processing and final stress relieving processing. Microstructure of molybdenum alloys shows elongated structure and fine distributions of composite particle. Compared with unalloyed molybdenum, the addition of MoSi2/rare earth oxide causes great improvement in the mechanical properties of molybdenum, especially its tensile strength at high temperature.
