| Abstract Scope |
The mechanical properties of near-β Ti-alloys are highly dependent on their microstructures, which often is composed of multiple phases and precipitates. The volume fraction, size, morphology, and distribution of these precipitates can significantly influence the final mechanical properties. Therefore, a complete and detailed understanding on phase transformations and microstructural evolution are crucial to optimize the mechanical properties for various applications. In this study, Ti-5Al-5Mo-5V-3Cr (Ti-5553) a near-β titanium alloy has been solution treated at two temperatures above and below the β-transus followed by series of artificial aging treatments at various times and temperatures to study the microstructural evolutions. Different phases were identified, and phase quantity were measured using X-Ray Diffraction and Scanning Electron Microscope. Micro-indentation hardness was measured and finally, an effort has been taken to correlate that with the associated microstructures. |
