Purpose: A study was conducted to investigate the dynamic recrystallization of commercially pure Titanium alloy during high temperature deformation in order to understand it further and enable expansion of its usage. Design/methodology/approach: Uniaxial tensile tests were carried out at 600, 750 and 800°C with different initial strain rates. Microstructure evolution during high temperature tensile testing was studied by using optical microscope and Electron Back Scattered Diffraction. Findings: It is found that this titanium alloys do not show good superplasticity at 600-800°C due to the rapid grain growth. Studies also show that the dynamic recrystallization took place at high temperatures. This process not only decreases the average grain size of the alloy but also increase the misorientation angle of the grain boundary. Practical implications: The investigations of dynamic recrystallization of commercially pure titanium alloy as well as related phenomena are important for achieving desired mechanical behavior of the material. Originality/value: The dynamic recrystallization phenomenon of commercially pure titanium alloy as well as related mechanism is investigated.
