Geometrically necessary dislocation density distributions in cyclically deformed Ti-6Al-4V

Abstract:

Cross-correlation-based electron backscattering diffraction analysis has been used to map lattice rotations in Ti-6Al-4V polycrystals deformed by load-controlled fatigue and dwell fatigue including a hold at maximum load. The lattice curvatures were used to form lower bound estimates of the geometrically necessary dislocation (GND) density distributions. In all cases the density of 〈a〉-type GNDs was much higher than for 〈c + a〉-type GNDs. As for tensile deformation the GND density histograms ...
