논문 초록 (Abstract)
A clear understanding of the factors controlling reproducible composite processing is critical for high temperature application. One approach to obtain stable phase combinations (i.e. compatibility) is to use a controlled interface reaction (in-situ layer design). An effective approach to control the reaction products and diffusion pathway by adding an extra component layer has been practiced and analyzed based upon the relative component fluxes. At the same time, the observed diffusion pathway has been examined in terms of a chemical potential framework, which can provide in assistance interpreting kinetic data in multicomponent systems. While component chemical potential values can increase and decrease through the interdiffusion reaction layers, the total free energy value will be decreased during the interdiffusion reaction. In order to examine the operating principles involved in the synthesis of in-situ composites, model ternary systems including potential materials such as TiAl and SiC have been investigated.
