In order to achieve the optimum combination of the strength and ductility in titanium alloys, it is of significant importance to study the critical factors determining the alpha microstructure. In this work, the 3D computational simulation and experimental characterization are used to study the grain boundary precipitation in titanium alloys. The nucleation and growth of grain boundary alpha precipitates was simulated using 3D phase field modeling. The 3D morphology of grain boundary alpha precipitates was characterized by the FIB serial sectioning and reconstructed using the MIPAP image analysis software. The influence of the inclination angle between the habit plane of the selected variant for grain boundary alpha and the hosting grain boundary plane in determining the morphology of grain boundary precipitates will be introduced. This work is supported by the National Science Foundation, grant CMMI-2122272.
