| چکیده | ||
| Ti–6Al–4V alloy has gained widespread popularity due to its extensive applications, including nuclear and aircraft structural components, machine parts, and notably medical equipment parts. Gaining a comprehensive understanding of the material's deformation behavior and microstructure evolution during the hot working process is crucial in order to attain the desired dimensions and the final mechanical properties of a product. In this study, the hot deformation behavior of the fully lamellar Ti-6Al-4V alloy was investigated using the hot compressive test at different temperatures of 700-1050 ◦C and strain rates of 0.001-1 s-1. The deformation stress, strain rate, and temperature were correlated using Arrhenius constitutive equations in α + β and β-phases. Finally, the activation energy values were calculated at almost 630 kJ/mol and 293 kJ/mol in α + β and β-phases, respectively. Based on true stress-strain curves, dynamic recrystallization was the dominant hot deformation mechanism at strain rates of 0.1 s-1 or lower. On the other hand, dynamic recovery occurred at a low temperature of 700 ◦C, and high temperatures of 1000-1050 ◦C with high strain rates of 1 s-1. The dynamic strain aging was visible as the serrated effects on deformation curves. The hot deformed microstructures of Ti-6Al-4V alloy were changed through geometric dynamic recrystallization, lamellar kinking and fragmentation, and globularization. Microstructural evolution at low temperatures immediately initiated after peak stress with dynamic recrystallization and lamellar kinking. At high temperatures of 850-900 ◦C, globularization was combined with other softening mechanisms, and the lamellar microstructure was changed to equiaxed grains. | ||
