Effect of temperature on elastic constants and dislocation properties of Fe 30% Al single crystals

The elastic constants of Fe 30% Al single crystals were determined using a resonance technique over the temperature range, 293–1173 K, of the observed yield strength anomaly. While the elastic shear anisotropy, Zener's factor, is high, A = 4.6–6.8, the factor related to a shear with respect to...
