Real components are usually subjected to variable amplitude fatigue, and yet the deformation micromechanisms that occur due to such load changes have barely been the subject of study. Here, unidirectionally rolled equiaxed Ti–6Al–4V plate was subjected to mixed dwell and variable amplitude low cycle...
