Abstract
The mechanical properties of the plates rolled with shear deformation are compared with those of conventionally rolled plates. The pair cross rolling is employed to introduce uniform shear strain through the plate thickness. The introduced shear strain and the equivalent strain are evaluated from both experimental and numerical analyses. A 12 mm thick plate with a fine ferrite grain under 2 μm is produced using the pair cross rolling mill, and tensile and the sharpy impact tests are carried out. The interesting effect of the shear deformation is discussed from the viewpoint of the tensile strength and the energy transition temperature. The result shows that the addition of shear deformation can become an effective method for improving the strength and the energy transition temperature of steel plates.
