Effect of strain-rate on the deformation response of D03-ordered Fe3Al
Source abstract
Abstract
Abstract The mechanical response of centrifugally cast Fe3Al with the composition Fe–27Al (at.%) containing micro-alloying additions of Nb, Zr, C, and B was investigated over a wide range of strain rates between 10−4 and 103 s−1 at room temperature. Tests were carried out in compression using a (i) screw-driven load frame, (ii) drop impact tester, and (iii) split-Hopkinson pressure bar at quasi-static, intermediate and dynamic strain rates respectively. Post deformation analysis was carried out by DSC, SEM/EBSD, TEM and micropillar deformation. In all instances, the stress-strain curves show initial hardening (∼first 5% plastic strain) followed by a plateau in stress. A loss in work-hardening occurs at the highest strain rates examined (>103 s−1) and is likely associated with shear localization; in addition, (2 1 ¯ 1 ) [11 1 ¯ ]-type twinning was observed at these high strain rates at room temperature. This observation is in line with previous theoretical calculations of the antiphase boundary (APB) energy. The consequence of a continuously increasing yield stress with strain rate and a loss in work hardening at the highest strain rates together yields a maximum in flow stress at the intermediate strain rate.
