چکیده انگلیسی
Blistering behavior in polycrystalline tungsten is investigated under low flux helium and hydrogen ion irradiation. Subsequent to irradiation, the grain orientations near (0 1 1), (1 0 1) and (1 1 1) planes on the surface are analyzed by SEM and EBSD. It is found that blister density is the greatest on the grain orientation near (1 1 1) plane, and the smallest on the grain orientation near (0 0 1) plane. Experiments suggest that blistering degree highly depends upon the grain orientation, blisters are easily formed on the grain orientation near (1 1 1) plane, and medium on the grain orientation near (1 0 1) plane, and the most rare on the grain orientation near (0 1 1) plane. The surface resistant orientation of tungsten is orientation near (0 0 1) plane. The atom binding energy in the crystal plane in combination with the channeling effect of adjacent crystal planes may play an important role for the difference of the surface morphology.
