The hot deformation behavior of A-286 superalloy has been characterized using hot compression experiments in the temperatures between 1000 and 1100 degrees C and strain rates varying between 0.001 and 0.1 s(-1). In addition, hot workability of this alloy has been analyzed by employing flow-localization parameter. The results show that both kinds of softening mechanism, dynamic recovery and dynamic recrystallization, occur during hot working, where at 1000 degrees C the main mechanism is dynamic recovery and at higher temperatures and strain rate of 0.001-0.01 s(-1) dynamic recrystallization takes place. Calculations demonstrates that this alloy mainly have a good workability for the utilized deformation conditions however, at temperatures around 1050 degrees C critical conditions may be raised and flow localized region could be formed.
