| Abstract Scope |
The mechanical performance of titanium alloys can be optimized by tuning the hcp structured alpha precipitates in a matrix of bcc structured beta phase. 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 3D experimental characterization are used to design the grain boundary alpha microstructure 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. |
