Deformation and Recrystallization Textures in Iron Aluminides
Abstract
Iron aluminides of different composition were deformed at high temperatures by extrusion through a round and rectangular die, approximating tension and plane strain deformation, respectively. Depending on temperature and composition dynamic recrystallization takes place. To investigate post-deformational recrystallization annealing treatments have been applied. Global and local textures were measured by neutron and electron back scatter diffraction (EBSD), respectively. The EBSD method allows the separation of deformation and recrystallization texture components. Moreover, the texture development is correlated with the microstructure evolution derived from EBSD mappings. The development of the deformation and recrystallization textures is discussed by means of different models on polycrystal deformation and recrystallization, respectively. Conclusions concerning the anisotropy of the elastic and plastic properties are drawn.
