Using Oim to Interpret the Dynamically Recrystallized Texture of a Low Stacking Fault Energy FCC Material

Abstract

Orientation imaging microscopy was performed on hot twisted polycrystalline 304 stainless steel specimens in order to study the characteristics of dynamic recrystallization (DRX) in low stacking fault energy FCC metals. The mesotextures of the recrystallized areas revealed that multiple twinning controls the formation of the microstructure, and the subgrain size distribution was found to be closely linked to that of the recrystallized grains. The grain sizes of the major DRX texture components were measured and relative growth factors were calculated. Finally, a deformation and recrystallization model based on the OIM observations and the steady state properties is described that simulates texture development during DRX.
