| Abstract Scope |
Rolling of powder compacts has been used to develop grain-orientated microstructures, especially for anisotropic magnetic material, but can also be applied to piezoelectric ceramics. To obtain a thick ceramic green sheet, powder rolling may be an effective way to actualize higher productivity, compared with a conventional process consisting of slip casting and subsequent laminating of thin sheets. However, the rolling condition to reach high orientation of plate-like ceramic particles, in bodies plasticized with organic binders, has not been studied sufficiently, and should be clarified based on the theoretical consideration. In this study, the effects of differential speed powder rolling on the orientation behavior of plate-like particles are examined by using the Folgar-Tucker model. The change in orientation angle distribution is computed under assumption of a simple velocity field in rolling process. It is shown that the shear deformation in advance of compression is effective to obtain higher degree of orientation. |
