چکیده انگلیسی
The properties and microstructure of pure Mo bars were investigated during upset-forged deformation. The results show that transverse elongation and microhardness of the draw-forged molybdenum samples are improved by upset deformation. After the reduction increases to 80%, the transverse elongation and microhardness of Mo bars are up to 5% and 235HV. The texture of ã110ã fiber in draw-forged Mo bars is changed to ã100ã fiber and ã111ã fiber during upsetting process. Meanwhile, equiaxed dislocation cells are formed in ã100ã oriented grains, and microbands are formed in ã111ã oriented grains. Many sessile dislocations are usually formed in ã100ã oriented grains and glissile dislocations are usually formed in ã111ã oriented grains. The fracture mechanism of these different grains is quite different.
