Abstract

A detailed study has been made of the thermal stability of aligned Al-Al3Ni eutectic after prior compressive deformation at room temperature. Compressive strains of between 6% and 50% were imposed perpendicular to the axis of alignment of the eutectic. Annealing of deformed and undeformed material at 883 K led to spheroidization of the Al3Ni rods at a rate which increased rapidly with increasing prestraining. Thus, for eutectic previously strained by 50%, almost complete spheroidization was observed after only 10 h at 883 K. The present behaviour was explained partly in terms of enhanced diffusion along matrix dislocations introduced during deformation.
