| Abstract Scope |
Strain transformable metastable beta titanium alloys, exhibiting transformation-induced plasticity (TRIP) and/or twinning-induced plasticity (TWIP), show excellent strain hardening and ductility in their single-phase beta microstructure, which is typically not seen in dual-phase (α + β) microstructures. This work investigates the influence of alpha phase fraction and distribution, induced by controlling the cooling rate from above the beta transus temperature, on the deformation behavior of TRIP-dominated Ti-10V-2Fe-3Al and TWIP-dominated Ti-7.5Cr-1Sn-1Fe alloys. An increase in alpha phase fraction led to an increase in the relative stability of the beta phase and decrease in the effective beta domain size, thereby enhancing the tensile yield strength of both alloys. The transition in deformation behavior from single-phase to dual-phase microstructures was studied using SEM-EBSD based techniques. |
