Influence of activated dislocations on recrystallization near grain boundaries in coarse-grained Fe-30Cr alloy

Compressive deformation was applied to a coarse-grained Fe-30Cr alloy polyc rystal at room temperature. Multiple slip occurred close to a grain boundar y Through the investigation of the activated slip systems, it was known tha t the dislocations which piled up against the grain boundary were mixed one s with a relatively large screw component. After annealing, many recrystall ized grains (RGs) formed close to the original grain boundary. The orientat ions of more than 80% of the RGs were related to the deformed matrices by r otations about (110) aves normal to each common cross slip plane of the act ivated dislocations. Strain induced boundary migration did not occur. The p referred orientation of RGs was discussed in connection with the activity o f slip systems.
