- OS0113 Grain Boundary Inclination Dependence of GN Dislocation Patterns in Bicrystal Model
抄録
A compatible-symmetric-type bicyrystal model and incompatible-type bicrystal models having inclined grain boundary were employed to conduct crystal plasticity analysis of unidirectional tensile tests, and we investigated changes in patterns of Geometrically Necessary dislocation (GND) bands when nominal strain was 1 %. The results showed that GND bands, where the inclination angle was about 45°, developed from the intersection point of the grain boundary with the upper or bottom edge, and the bands inclination was unalterable independently of angles of the grain boundary inclination. On the other hand, sign of densities of GN dislocations within the bands was changed when the grain boundary inclination was changed from 45° to 46°. This is because the mechanical restraint at the upper and bottom edge and the grain boundary strongly affects formation of GND bands rather than the inclination of grain boundary.
