Abstract

Microindentation has been used to characterize the indentation behavior of aluminum processed by ECAE (equal channel angular extrusion). The bending angles of the ECAE dies are 90°, 120° and 150°. Using dislocation dynamics, it is found that the initial dislocation density increases with the decrease in the bending angle at the macroscopic yielding during the indentation. For the same indentation load, the plastic energy dissipated in the indentation increases with increasing bending angle.
