説明

The combination of the slip systems necessary for the plane strain deformation can be determined by the theories proposed by Taylor and Bishop-Hill. But the resolved shear stresses of the slip systems necessary for the plane strain deformation are not always high. In crystals with such a situation, the deformation band is expected to be introduced to compensate the inactivity of the necessary slip systems with small shear stress. The orientations of the aluminium single crystals satisfying the condition mentioned above were previously determined by calculation. Some of them, having {011}, {111} and {112} as the compression plane, were prepared for the rolling experiments. Except for the {110}⟨112⟩ orientation, the idea proposed for the appearance of the deformation band was experimentally shown to be valid. Co-operation of two sets of slip systems makes the {110}⟨112⟩ crystal possible to be deformed without operation of the necessary slip systems with small resolved shear stress. Consequently, in the {110}⟨112⟩ orientation the plane strain deformation would not need the deformation band.
