In this study, the recrystallization process of selective laser melted (SLM) commercially pure titanium (CP-Ti) was followed by a quasi-in-situ electron backscatter diffraction (EBSD) method at 800 °C and 700 °C. Abnormal grain growth (AGG) initially emerges at the beginning of annealing at 800 °C a...
