Hollow spherical Ti–Al–C clusters have been prepared by combustion synthesis in air with the assistance of mechanical activation. The clusters have a two‐layered shell structure, where the outer layer consists of Ti–Al–C ternary phases and the inner layer is composed of TiC grains. The reaction procedure and microstructure evolution during the combustion reaction is discussed. It is proposed that the presence of a Ti–Al melt is important for the formation of the hollow spherical clusters.
