A New Approach to Materials Design and Development for Advanced Materials : Interfacial Architecturein Material Systems

Abstract

A new approach to materials design and development for advanced materials is discussed which is defined Interfacial Architecture for material systems. Structure-dependent properties of individual grain or interphase boundaries can be effectively utilized to produce a polycrystal system with high performance by designing and controlling the grain boundary character distribution (GBCD). Recent applications of the concept of Interfacial Architechture through grain boundary design and control for advanced materials are introduced. A prospect of materials design and development by Interfacial Architecture is discussed.
