Abstract
The tensile strength of an Ni-Al-Cr-C eutectic composite which has an Ni-rich matrix containing a dispersion of Ni3Al precipitates has been measured both with a fully-aligned and a cellular microstructure. The fully-aligned eutectic behaves as a simple metal-matrix composite. The reduction in strength of the cellular eutectic due to the off-axis reinforcement is shown by a simple analysis to result from weakness of the fibre/matrix interface which is borne out by observations of the fracture surface.
