Microstructure Evolution of TC16 Titanium Alloy During Hot Deformation in β Phase Field
Hot deformation behavior and microstructure evolution of TC16 titanium alloy in β phase field were studied in the strain rate range 0. 001-10 s-1 by means of isothermal compression. Features of true stress-true strain curves during hot deforming were analyzed. EBSD technique was used for obtaining the boundary misorientation distribution after deformation. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were used for microstructure analysis. X-ray diffraction pattern was used for phase identification. The results demonstrate that TC16 titanium alloy undergoes dynamic recrystallization, dynamic recovery and phase transformation during the process of hot deformation. Microstructure can be improved through a large amount of deformation in the β phase field followed by annealing in the α+β phase field.
