In order to develop the high strength materials, the forming process with large strain is one of available processes. The authors have developed the repeated shear deformation process with side pressure under high hydrostatic pressure. In this study, the aluminum base materials (pure aluminum and Al-Mg alloy) are deformed by shear deformation process with or without side pressure, and the effect of side pressure for properties of those materials are investigated. Vickers hardness had no effect on the side pressure, however, the side pressure influenced bulk form of workpiece and deformation texture. After 10 times shear deformation process with side pressure, fine grain structures were obtained. Tensile strength increased about twice as those of as-received materials after 10 times deformation process.
