Sažetak
Hot compressions tests of Inconel 625 superalloy were conducted using a deformation dilatometer to the strain level of 0,7 at 1 050 °C, with a different strain rate. Optical microscope and electron backscatter diffraction technique were used to investigate the microstructure evolution and nucleation mechanisms of dynamic recrystallization. Microstructural evolution of Inconel 625, deformed to the strain level of 0,7 at 1 050 °C, reveals that the size of the dynamic recrystallization (DRX) grains and the fraction of DRX increase with the decrease in strain rate. At the strain rate 10 s-1, the grain sizes are mainly located in the size below 20 μm, indicating that nucleation of DRX was dominant due to the combined effects of high stored energy and short deformation time for grain growth at high strain rate.
