Recrystallization and grain growth are important microstructural phenomena in commercial titanium alloys. In this study, we concentrate on recrystallization and grain growth of the dominant α-phase. The static recrystallization and grain growth behavior of model binary α-Ti alloys were studied by performing room temperature compression tests followed by recrystallization heat treatments. EBSD techniques were used to quantify recrystallization along with texture and grain size evolution. Increasing aluminum content was observed to lead to significantly slower recrystallization kinetics. The effects of processing conditions and solute concentration on the recrystallization kinetics are analyzed and modeled using the JMAK model along with a physically based model. Grain growth kinetics were characterized in 3D using serial sectioning microscopy and compared with 2D results. The results from these experimental studies have been used to parameterize a phase-field model of recrystallization and grain growth in single phase titanium.
