抄録

In this study, we investigate the formation of plastically deformed microstructure in a single crystal copper during micro-indentation tests. The micro-indentation tests of single crystal copper specimens were conducted by using a knife edge tool made of diamond. In order to reveal the plastic deformation behavior of the single crystal copper specimen, the crystal orientation around the indented groove was analyzed by SEM-EBSD and the dislocation microstructure in the specimen was observed by high-voltage transmission microscope (HVTEM). Through these experiments, the crystal rotation behavior and the dense dislocation-cell structure in the specimen were clarified.
