摘要：
Hot deformation behavior and the microstructural evolution of Inconel 625 superalloy plates are investigated by hot compression tests in a range of working temperatures (800-1050 degrees C) and strain rates (0.001-1 s(-1)). The microstructural observation shows that a strong texture forms when the processing temperature is below 950 degrees C, whose intensity decreases with the increases of the temperature, and it disappears when compressing above 950 degrees C. During the compression test, twin-related dynamic recrystallization (DRX) occurs in the investigated temperature range, and the intensity of twin-related DRX increases with the increases of the temperature. In addition, as the temperature increases, the intensity of continuum DRX decreases.
