Abstract Scope |
In this study, the role of composition and microstructure on the mechanical behavior of three advanced titanium alloys – Ti-6Al-4V, Ti-6Al-2Sn-4Zr-2Mo, and Ti-6Al-2Sn-4Zr-6Mo is investigated using multiple characterization techniques. Their microstructures were characterized using backscattered electron (BSE) images and their deformation behaviors were explored using high-energy x-ray diffraction in situ uniaxial tension tests. The evolution and hardening responses of the lattice strains for the α and β phases are discussed. Stress-induced β→ α" phase transformation was also observed in Ti6246, which was captured during the in situ diffraction experiment. Results from this study provide insights into the relationship between microstructure, composition, and mechanical behavior. |
