Superplasticity - A Fundamental Investigation on Deformation Mechanism and Cavitation Phenomena

Abstract

Superplasticity at high strain rates was obtained in mechanically alloyed aluminum IN90211. The high rate was due to the fine grain size. A threshold stress analysis, combined with SEM and TEM observations permitted the deformation mechanisms to be determined. Very little cavitation was observed, due to the grain morphology, and the deformation mechanisms that are operative. Superplasticity, Mechanical behavior, Deformation mechanisms, Cavitation phenomenon, Adiabatic heating, Threshold stresses, Dispersion strengthening.
