Abstract:

The high temperature deformation behavior of 2101 duplex stainless steel has been investigated in the temperature ranges of 900-1150°C and strain rate ranges of 0.001-1s^-1. Increasing strain rate from 0.001 to 1s^-1 was contributed to austenite dynamic recrystallization (DRX) of specimens with deformation temperature of 900°C, but the DRX effect was weakened due to coarsening of equiaxial grains by increasing deformation temperature to 1050 and 1150°C. The effect of ferrite dynamic recovery (DRV) was enhanced with deformation temperature from 900 to 1050°C, then which was weakened with further increasing deformation temperature to 1150°C. By regression, the deformation equation and activity energy of 457.93 kJ/mol in these deformation conditions was obtained.
