抄録

Non-isoaxial bicrystal specimens with various twist boundaries and “pseudo-bicrystal” ones which consist of two component single crystals and have no compatibility were prepared. From the relations between the twist angle and the difference in flow stress between the bicrystal σ_Bi and the pseudo-bicrystal σ_A+B, the effects of various twist boundaries on the tensile deformation of the bicrystals were examined.<BR>The results were similar to those of the bicrystals with the tilt boundaries i.e. in a large number of the bicrystals with the twist boundaries of less than 30° twist angles, σ_Bi−σ_A+B<0 were obtained at least near 2×10⁻³ strain. The work-hardening rate of the bicrystal was larger than that of the pseudo-bicrystal.<BR>As the new major factors of the effects of grain boundaries on the plastic deformation, the grain boundary structure itself and their relative orientation with the direction of applied stress and the slip vectors should be added.
