The as-solidified and annealed microstructures of a rapidly solidified Al 96.52Fe 2.03Si 0.64Ti 0.46C 0.35 alloy were evaluated. The as-solidified microstructure comprised an intracellular uniform, fine-scale dispersion of Al 6Fe phase in α-Al and elongated amorphous particles located along the cell boundaries, with approximately 0.46 at.% Ti and 0.35 at.% C saturated in the α-Al. During annealing, the amorphous phase transformed into α T-AlFeSi phase, and some of the Al 6Fe dispersoids increased in size while others were replaced by Al 3Fe particles. After annealing at 773 K for 5 h, face centered cubic TiC particles, of approximate atomic composition Ti 5C 4 and lattice parameter 0.424 nm, precipitated in the α-Al matrix. Moreover, there is a cube-cube orientation relationship between Ti 5C 4 and the α-Al matrix with a disregistry of δ = 0.05. The formation mechanism of this TiC is discussed.
