چکیده انگلیسی
The relationship between the development of the crystallographic orientation and the grain growth behavior were studied. The degree of orientations of the green compacts and sintered samples were evaluated by the Lotgering factor. The f(0Â 0Â l) of all the samples were drastically increased with the increasing applied magnetic field strength. The f(0Â 0Â l) of the samples sintered at 1223Â K were improved in comparison to those of the green compacts. However, the f(0Â 0Â l) value of the samples sintered at 1273Â K were not increased at 4 T or lower. To characterize the grain growth process, these samples were analyzed using electron backscatter diffraction (EBSD). The sintered samples prepared in the magnetic field at 4 T or lower showed abnormal grain growth. The samples with an applied magnetic field of 8 T or higher had no abnormal grain growth. It was revealed that the orientation angle of the particles has an effect on the grain growth.
