报告摘要

Abstract:

Technologies to create/exploit/enhance anisotropic properties of materials have recently attracted attentions from the engineering demands for devices and structures with high and/or unique performances. One finds in nature, many anisotropic-structured materials such as lumbers and seashells as a result of oriented biological growth. From past to present, carpenters and craftsmen have known well anisotropic properties of the bio-materials and fabricated, for example, a 1300 year long-lasting wooden tower and gorgeous jewelry boxes with mother-of-pearl-inlay. We have been interested in the design of unique and useful artificial micro/meso/nanostructures such as oriented polycrystals and nano-composites. Control of growth or scaling direction is the key in the processing design for the anisotropic materials. Quantitative characterization and simulation techniques for materials anisotropy are also important for the evaluation of processing and prediction of properties. In this talk, several examples of materials we designed and fabricated in TCRDL are presented with their background science and technologies. The focus is especially located on the texture engineering of bulk oxide ceramics for dielectrics, piezoelectrics and thermoelectrics with enhanced properties by using the reactive-templated grain growth (RTGG) method. Toyota Technological Institute is also introduced as a unique engineering college with a cooperative graduate school with Toyota CRDL.
