| Abstract Scope |
Improving both strength and ductility in titanium alloys remains challenging, particularly for aerospace applications. Here, we present a multi-pass laser surface treatment to create functionally graded microstructures in alpha + beta Ti-6Al-4V. The resulting surface region exhibits transformed morphologies, including fine basketweave structures, α′ laths, and core-shell-like phase distributions, tailored through sequential processing. This engineered gradient significantly enhances mechanical performance, simultaneously improving yield strength and ductility relative to untreated alloys. These promising results highlight that precise tuning of laser-based strategies to control microstructural gradients and phase morphology for improved mechanical properties. Ongoing work explores further tuning of these gradients and their role in governing deformation and damage resistance. |
