SUMMARY The microstructure of a 2024 type aluminium alloy, reinforced with 13 vol.% SiC particles, and made by a spray technique, has been investigated by transmission electron microscopy and X‐ray microanalysis in the as‐extruded and T6 conditions. High resolution electron microscopy studies and energy‐dispersive X‐ray spectrometry microanalysis were performed on the interfaces between the SiC particles and the metal matrix. The interfaces were found to be abrupt: some exhibit an amorphous layer, rich in oxygen; in many others, silver‐rich crystallites have grown coherently on the SiC particles.
