    • Abstract
  • Mo-30 W molybdenum alloy bar was prepared by powder metallurgy technology. The recrystallization behavior of Mo-30 W molybdenum alloy bar was analyzed by using tensile properties measurement, hardness measurement, optical microscope (OM), scanning electron microscope (SEM), and energy dispersive spectrometer (EDS). The results show that, the tensile strength of Mo-30 W molybdenum alloy bar at 1600 ℃ is 170 MPa and the elongation is 10% due to the solid solution strengthening and deformation strengthening of W, the high temperature mechanical properties are significantly improved. In the range of 1300~1500 ℃, the strength and hardness of Mo-30 W molybdenum alloy keep stable and then significantly decrease with the increase of temperature. The Mo-30 W molybdenum alloy are completely recrystallized at 1500 ℃, the tensile strength is 385 MPa, the Vickers hardness is HV10 185, and the tensile strength and hardness value reach the lowest.
