Abstract
The nature of defects present in deformed titanium is studied by combining the positron annihilation technique and computer simulation. By performing isochronal annealing between room temperature and 1123 K it is shown that the lifetime decreases up to 700 and stays roughly constant up to 1000 K, achieving the bulk value at 1123 K. These results are interpreted as positron trapping at zonal dislocations present at twin boundaries, as inferred from computer simulation studies. Die Art der Defekte...
