Abstract
An analysis is made of experimental data on the high-temperature spheroidization of Fe, Cu2S and Cu2O rods in the FeS-Fe, Cu-Cu2S and Cu-Cu2O eutectics. The work indicated that breakdown in FeS-Fe took place by diffusion in either the matrix or in the rod-matrix boundary. In contrast, spheroidization in Cu-Cu2S probably depended on transport in either the rod or the interphase boundary, and in Cu-Cu2O breakdown took place by diffusion in the eutectic rods only. The latter results confirm that the diffusivities of atomic species in eutectic matrices are not necessarily good guides for predicting the high-temperature stabilities of fibrous, eutectic composites.
