| Abstract Scope |
Ti-6Al-4V (wt. %) is an α-β Ti-alloy widely used in structural aerospace applications due to its high specific strength and corrosion resistance. Quenching and Partitioning (Q&P) is a two-stage heat treatment process applied to steels that produces novel microstructures with improved mechanical properties. Implementing Q&P heat treatment processes in Ti-6Al-4V has the potential to produce microstructures with tailored phase fractions and compositions of α, β and martensite. Controlled dilatometric heat treatments, guided by thermodynamic calculations, were performed to investigate the impact of Q&P parameters on microstructure development, including phase fractions and chemical partitioning. Here we highlight recent efforts to understand how Q&P heat treatments impact the resulting microstructures and strength-ductility combinations in Ti-6Al-4V and how these insights can be used to tailor Q&P processing parameters. |
