説明
The objective of the present study was to find the orientation relationship between a recrystallized grain at its initial stage and a deformation microstructure in a non-uniformly deformed copper single crystal.<br> A tensile strain of 25% was applied to a 〈110〉 copper single crystal sample in which shallow grooves were made at both side faces before the tensile test to promote non-uniform deformation. A thin disc specimen prepared from the deformed sample was annealed in a high vacuum. A scanning electron microscope (SEM)/electron backscatter diffraction (EBSD) method was used to analyze the orientations of deformed and annealed states.<br> There are two primary slip planes of the largest Schmid factor in a face-centered-cubic metal single crystal deformed along a 〈110〉 direction. In the present copper single crystal sample, both right-up and right-down band-like regions are formed in which either of the primary slips was activated. The arrangement of band-like regions on the overall sample surface was almost symmetrical. Between band-like regions, there were regions of patchy slip appearance, consisting of double-slip and single-slip areas. The band-like regions were rotated so that the slip directions moved towards the tensile axis. On the other hand, the rotation of patchy regions was relatively small.<br> In the disc specimen annealed at 833 K, a recrystallized region was formed at the boundary between band-like and patchy regions. The recrystallized region consisted of two types of recrystallized grains having a twin relationship each other. Both types of recrystallized grains had an 〈111〉-rotated orientation relationship with the band-like region.<br>
