Abstract

The mechanical properties of near β Ti-alloys are highly dependent on their microstructures, which often 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 is 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 a temperature above 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 was measured using scanning electron microscope and energy dispersive X-ray spectroscopy. Micro-indentation hardness was measured, and finally, an effort has been taken to correlate the mechanical property with the associated microstructures.
