The spatial distribution of α phase in laser melting deposition additive manufactured Ti-10V-2Fe-3Al alloy

In this study, the Ti-10V-2Fe-3Al alloy specimen has been fabricated by laser melting deposition additive manufacturing technique. Three special microstructures are found. A tetrahedral distribution model of α phase and the simulated microstructure have been built to explain the formation of special microstructures. And the simulated microstructure based on the tetrahedral distribution model has been verified by real microstructure and Electron Backscattered Diffraction (EBSD).321
