Abstract

Scanning and transmission electron microscopy methods were used to investigate a composite with an aluminium matrix reinforced with alumina and nickel aluminide particles, obtained from powder mixtures during unidirectional two-stage pressing under vacuum. At the interface between the particles and matrix, Al₃Ni aluminide was identified, irrespective of the aluminide particle microstructure. An increase in oxygen concentration at the interface was found, compared to its concentration in the aluminium matrix.
