The Effect of Interfaces on the Behavior of In-Situ Metallic Composites

Abstract The morphology and properties of an in-situ metallic composite depend on the nature of the interfaces separating its constituent phases. In this paper, four models for these interfaces are considered: coherent, semi-coherent, cusp-oriented and noncoherent. The consequences of each model with respect to composite morphology, load transfer, morphological stability at elevated temperatures and mechanical behavior are discussed.
