| Abstract: | Applying compacting process in powder metallurgy, high pure Mo powder was prepared and sintered, then the sintered body was upsetted. The deformation and densification law of Mo powder sintered body was studied under different initial conditions, including relative density, relative height and friction factor, which put forward a lot of experimental dams for improvement of Mo traditional technology and optimal design of preform blank and die. |
