Abstract Scope |
Clarifying micro-mechanisms that cause strain heterogeneity in multi-phase titanium (Ti) alloys is of fundamental importance for more damage-resistant microstructure design. The occurrence of mechanical twinning increases the difficulties in characterization due to its spatial and time dependence. In this study, we combine the insights provided by in-situ microstructure-based digital image correlation (μ-DIC) and in-situ synchrotron X-ray diffraction (SXRD) to shed more light on the effects of mechanical twinning on strain localization and damage evolution in an (α+β) alloy. Strain localization mechanisms in the alloy are investigated in a timely and spatially resolved manner. The potential use of mechanical twinning to delocalize plastic strain will also be discussed. |
