摘要

Advancements in creep deformation mechanism analysis have the potential to improve future lightweight material capabilities. This work details a novel experimental technique for in-situ observation of creep deformation mechanisms grain rotation and dislocation motion. High-resolution digital image correlation was taken during creep in-situ using TiMo15, a metastable ß-Ti, as a model lightweight material. The creep testing captured microstructure deformation mechanisms and mesoscale deformation for creep characterization. Dislocation motion and grain rotation were identified as dominant deformation mechanisms. The use cases for the generated data are discussed with respect to modeling and impact on experimental mechanics research.
