Abstrakt

Defect processes during isothermal annealing of rapidly quenched Cu (from 1000°C) and isochronal annealing of quenched (from 1400°C) and deformed Ni (20% rolled at room temperature) have been investigated by residual resistivity and positron lifetime measurements. In Cu a transformation of vacancy loops of the Frank type into loops of split Shockley partials was concluded. In Ni the growth of ultrasmall stacking fault tetrahedra could be the dominating process in vacancy annealing.
