| Abstract Scope |
The diverse microstructural combinations in two-phase titanium alloys have enabled a profuse platform in tailoring the corresponding mechanical performances. The plastic deformation coordination between α and β phases is of fundamental significance in affecting the macroscopic load-bearing responses, yet, the underlying deformation micro-events especially their contribution to strain localization and partition still remain elusive and deem detailed considerations. In this presentation, by studying a Ti-Al-V-Fe (α+β) alloy via integrated in-situ digital image correlation (DIC), in-situ synchrotron X-ray diffraction, and crystallographic calculation, we aim to showcase the exploration of the following three fundamental topics: (1) what are the deformation micro-events that governing strain localization inception? (2) how do strain localization and/or its partition evolve with respect to plastic straining? (3) how do the foregoing deformation micro-events affect damage nucleation and thereby macroscopic failure? Broader indications for mechanistically-guided microstructural design will also be included. |
