The present paper deals with the interfacial phenomena of two-phase materials, more specifically, with the interaction between molten metals and cemented carbides. In spite of the technical importance in various fields, very little is known on the spreading and reaction of liquid on and with two-phase materials. Brazing of cemented carbides is one of the examples. It is shown in our early work1) that the structure of reaction zones obtained by heating cemented carbides in contact with molten copper is not explained simply by referring to the phase relationships in the system of interacting components, copper and cobalt, and that the reaction behavior depends on the nature of cobalt/carbide phase boundary as influenced by the parameters such cobalt and carbon content and carbide composition.
