| 英文摘要 | The damages of implanted helium ions together with energetic neutrons in tungsten is concerned under the background of nuclear fusion related materials research. helium is lowly soluble in tungsten and has high binding energy with vacancy. in present work, noble metal au ions were used to study the synergistic effect of radiation damage and helium implantation. nano indenter and the doppler broaden energy spectrum of positron annihilation analysis measurements were used to research the synergy of radiation damage and helium implantation in tungsten. in the helium fluence range of 4.8 x 10(15) cm(-2)-4.8 x 10(16) cm(-2), vacancies played a role of trappers only at the very beginning of bubble nucleation. the size and density is not determined by vacancies, but the effective capture radius between helium bubbles and scattered helium atoms. vacancies were occupied by helium bubbles even at the lowest helium fluence, leaving dislocations and helium bubbles co-exist in tungsten materials.
