소둔시편 및 소둔 후 냉간가공한 하프늄시편에 대하여 양전자수명을 조사하였다. 소둔시편에서의 양전자수명은 187
Positron annihilation characteristics and microhardness of 25% cold worked and isochronally annealed hafnium specimens were measured to study recovery and recrystallization stages of hafnium specimens. The annihilation lifetime of positrons in hafnium has been measured for the distinct cases of annihilation in the annealed lattice and annihilation after trapping at lattice defects generated by cold deformation at room temperature. The annihilation lifetime in the annealed lattice was 187
