演講摘要：

In the present study, oligocrystals of Crofer® 22 H ferritic steel were obtained as experimental material at 1075 °C after 22 min of annealing. The effect of the grain orientation was investigated on deformed microstructures and slip patterns of the oligocrystals. Electron backscatter diffraction (EBSD) measurements were performed on coarse ferrite grains after being subjected to 3%, 6%, and 10% tensile deformation. The kernel average misorientation was used to identify the activated slip planes and deformation patterns. The activated slip planes, called anomalous slip planes here, do not follow the Schmid’s law and depend on the orientations of oligocrystals.
