Abstract
The behaviour of the ordered alloy Zr3Al was investigated by transmission electron microscopy following ion bombardments at temperatures ranging from 30 to 850 K. Utilizing high energy(0.5–2.0 MeV) C+, N+ and Ar+ ion bombardments, observations were made of the irradiation-induced transformation from the ordered → disordered → amorphous states. Information about individual damage cascades was also obtained using both high energy (C+. N+ and Ar+) and low energy (15–120 keV Cu+) ion bombardments.
