Dislocation Core Structures and Mechanical Behavior of DO22 Type Alloys
Published online by Cambridge University Press: 26 February 2011
Abstract
We investigate the structures of dislocation cores in a model DO22 type intermetallic alloy in the absence of external stresses. The tetragonal distortion produces sessile configurations of superpartial dislocations even when the energies of planar faults are reasonably low. The influence of the core configurations on the mechanical behavior at low temperatures is discussed.
