不同成分的铝化铁在高温下通过圆形和矩形模具挤压变形，分别近似拉伸和平面应变变形。根据温度和成分，会发生动态重结晶。为了研究变形后再结晶退火处理。分别通过中子和电子背散射衍射（EBSD）测量全局和局部纹理。 EBSD 方法可以分离变形和再结晶织构成分。此外，纹理的发展与 EBSD 映射得出的微观结构演化相关。分别通过多晶变形和再结晶的不同模型讨论了变形和再结晶织构的发展。得出了关于弹性和塑性性能各向异性的结论。
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.
