Abstract

Tensile properties of B2-type Fe-39mol%Al single crystals have been investigated between room temperature and 923 K. Positive temperature dependence of yield stress was observed in all the orientations examined. Orientation-dependent phenomena in the temperature range where temperature dependence of yield stress is positive, viz., orientation dependences of yield stress and critical resolved shear stress (CRSS), peak stress and peak temperature, and serrated flow behavior, shows trends opposite to those obtained in compression by our previous work. Based on the present results, it is concluded that those orientation-dependent phenomena represent intrinsic characteristics of deformation behavior associated with the positive temperature dependence of yield stress.
