Abstract
Tension-compression asymmetry of pseudoelasticity in Fe-23.0at.%Al single crystals with the D03 structure was quantitatively examined by analyzing stress-strain response during tension-compression loading. The crystals demonstrated large pseudoelasticity associated with to-and-fro motion of 1/4ã1Â 1Â 1ã superpartial dislocations dragging antiphase boundaries. Pseudoelasticity based on {1Â 0Â 1} slip showed little tension-compression asymmetry while an activation of {2Â 1Â 1} slip resulted in the asymmetry depending on the moving direction of 1/4ã1Â 1Â 1ã superpartials with a screw character during loading and unloading.
