英文摘要 | The true stress-strain curves and constitutive equations of 347H austenitic stainless steel were obtained via high temperature compression tests with the temperature range of 850 degrees C-1250 degrees C and the strain rate range of 0.01 s(-1)-10 s(-1). We have studied the microstructure evolution and nucleation mechanism of dynamic recrystallization by the electron backscatter distribution technique (EBSD), and the results show that the process of dynamic recrystallization consists of nucleation and growth. At high strain rate (10 s(-1)) and low temperature (< 1150 degrees C), the grain size increases with the increase of temperature, while the deformed grain gradually transform to recrystallized grain. When the temperature reaches 1150 degrees C, the complete dynamic recrystallization occurs and the volume fraction of recrystallized grains reaches the maximum. In addition, the necklace structure has confirmed the existence of discontinuous dynamic recrystallization, while the transition from low-angle grain boundaries to high-angle grain boundaries has confirmed the existence of continuous dynamic recrystallization. |
