| Abstract Scope |
This work presents the methodology, results, and potential impact of a novel grain refiner development strategy aimed at enhancing microstructure and texture control in metal additive manufacturing (AM).
The AM of Ti-6Al-4V, a critical alloy for biomedical applications, particularly implants, is hindered by columnar grain growth and strong texture formation, resulting in anisotropic mechanical properties. To address these challenges, a novel alloy development approach incorporating tailored grain refinement strategies has been employed.
Through tailored alloying techniques and optimized mixing methods, this approach aims to suppress columnar grain formation, thereby achieving isotropic material properties and improved mechanical stability. Initial findings from as-cast alloys produced via arc melting show 60% grain refinement, indicating promising improvements in nucleation rate and inhibition of grain growth, while maintaining microstructural uniformity and mitigating texture. These findings pave the way for producing Ti-6Al-4V implants and components with refined microstructures and enhanced mechanical performance. |
