Development of computational framework for titanium alloy phase transformation prediction in laser powder-bed fusion additive manufacturing
In conjunction with bare metal single laser track validation experiments, a computational
framework is proposed to accelerate the design and development of new additive
manufacturing (AM) specific alloys. Specifically, Additive Manufacturing-Computational Fluid
Dynamics (AM-CFD) and Calculation of Phase Diagram (CALPHAD), were combined to
predict location-specific β→ α phase transformation for a new Ti-Al-Fe-alloy. This modeling
work was validated by rigorous spatially resolved synchrotron-based X-ray diffraction …
