Ti-6Al-4V is one of the most promising biomaterial compared to other alloys used for biomedical application. Electron Beam Additive Manufacturing (EBAM) process is a rapid solidification process and the properties of the material depends on the solidification behaviour as well as the microstructure of the build material. Thus, the prediction of part microstructures during the process may be an important factor for process optimisation. In this study, a phase field model is developed for microstructure evolution of Ti-6Al-4V biomaterials produced by EBAM process. The simulation results are compared with the analytical model and experimental findings by measuring the spacing evolution under the solidification condition.
