Displacement reactions may play an important role in in situ processing technologies for the production of metal-ceramic composites. To better understand such reactions displacement reactions between NiO and Al were studied at high temperatures. Different reaction layers with periodic structures were observed involving Al{sub 2}O{sub 3}, Al{sub 3}Ni, Al{sub 3}Ni{sub 2}, Ni and Al. The experimental observations are presented and discussed with regard to the reaction mechanism.
