| Abstract Scope |
Recently, metastable β titanium alloys exhibiting transformation-induced plasticity (TRIP) and twinning-induced plasticity (TWIP) have gained significant attention due to their excellent strength, ductility, and strain-hardening capabilities. In this work, we investigated the deformation microstructure in a cold-rolled Ti-12Mo (wt.%) alloy employing scanning electron microscopy (SEM), conventional transmission electron microscopy (TEM), and aberration-corrected scanning/transmission electron microscopy (ACSTEM). The complex microstructure in the cold-rolled Ti-12Mo, featuring high density of dislocations and multiple deformation twinning systems, was revealed. Novel high-index deformation twins, in addition to the conventional {332}<113> and {112}<111> deformation twins, were identified through the SEM-EBSD analysis. Nanoscale structures near the twin-matrix interface, including ω and α’’ martensite precipitates, were characterized using TEM and ACSTEM, offering new insights into deformation twins. This presentation will provide a comprehensive analysis of the simultaneous TRIP and TWIP effects, highlighting their roles in achieving enhanced mechanical performance. |
