Abstract

Isochronal annealing of quenched commercial pure Al (99.5%) and Al-1wt.% Mn was performed between room temperature and 560 °C. The annealing of defects was studied using positron lifetime and Doppler broadening techniques. The behaviors can be divided into three stages: recovery, partial recrystallization, and complete recrystallization. The results suggest that a strong interaction between Mn atoms and vacancies in Al would retard the vacancy recovery from quenching. The Mn atoms enhance the nucleation of vacancy clustering in Al.
