AbstractThe hot deformation behavior of GH3535 superalloy was investigated by hot compression tests in the temperature range of 1000-1200 degrees C and strain rate range of 0.01-50 s(-1). The activation energy is about 356.3 kJ/mol, and the flow curves and processing map were developed on the basis of experimental data. The processing map exhibits a stable domain which occurs in the strain rate range of 0.01-1 s(-1) at all the temperatures and a instable domain which occurs in the strain rate range of 1-50 s(-1). Microstructural observations reveal that the full dynamic recrystallization (DRX) occurs in the conditions of (1150 degrees C, 0.01 s(-1)), (1200 degrees C, 0.01 s(-1)) and (1200 degrees C, 0.1 s(-1)) with different grain sizes and undissolved carbides. The flow localization and cracks occur in the regime of flow instability.
