1. Plastic deformation of dispersion hardened S.A.P. alloys-dislocation emission and sink phenomena.

Author

Falzoni, G., Gondi, P., Patuelli, C., and Tognato, R.

Abstract

Comparative observations were carried out on the plastic deformation characteristics of cold-rolled and recrystallized S.A.P. sheets, particular attention being given to the apparent and true activation volumes and energies. The higher flow stresses of the cold-rolled specimens are interpreted on the basis of a dislocation sink and emission model, by assuming that the sink rate is conditioned by the dislocation tangles pinned against the grain boundaries. Recrystallized sheet strength and dislocation emission processes are discussed in terms of conservative climb and backstresses due to dislocations pinned by the oxide particles.
