【 摘 要 】

Qualitative and quantitative microstructure descriptions of crystalline materials are crucial for characterization and better understanding of the mechanisms of deformation and recrystallization processes. In this study orientation mapping in SEM and TEM were applied to investigations of materials after plastic deformations by means of cold rolling and hydrostatic extrusion (HE) methods. Statistical analysis of local orientation, texture and grain boundary characterization were done for chosen materials of different symmetry like cubic aluminium and hexagonal titanium with high resolution capability down to a few square nanometres. It was proved that TEM / Orientation Mapping (OM) investigations can be successfully applied for complementary analysis to conventional SEM/EBSD.
