| Research Abstract |
Developed alloys, CCM alloys, have been forged on the basis of the Processing map in order to optimize condition of hot forging. Processing map has been constructed in detailed by considering observation of microstructure using EBSD, XRD and TEM. We have revealed that the microstructure observation and consideration of processing map are in good agreement; Instability map can be used to identify the occurrence of the dynamic recrystallization.
