Modeling tools have been developed for the prediction of microstructure evolution and mechanical properties of forged titanium components. These tools include (1) beta grain growth model for the heating of Ti-6-4, (2) beta grain size evolution model for beta forging of Ti-6246, (3) alpha growth model for the grain size evolution during heat treatment of Ti-6-4; and (4) Neural network mechanical property model for selected titanium alloys. The application of modeling tools in forging and heat treatment process design made it possible for the selection of the optimum process for the manufacturing of titanium components for aerospace applications.
Models for prediction of microstructure evolution and mechanical properties of forged titanium were developed and implemented in various titanium components for aerospace applications. Models, demonstrations and applications will be discussed and presented.
