Grain scale micromechanics have received significant research efforts to determine active deformation processes and how they govern the mechanical behavior. In this presentation, we report a major role of “ghost” structures inherited from the processing history that govern the deformation behavior at the mesoscale in Ti alloys. Several examples of deformation heterogeneities at the mm scale, resulting from the scanning strategy in additively manufactured materials, from microtextured regions in α+β alloys and from β grains in metastable β alloys, were experimentally characterized using in situ testing in scanning electron or optical microscopes. The relation with the macroscopic mechanical behavior is discussed and a mechanistic understanding of the experimental observations is provided using advanced computational and microstructure generation techniques.
