TEM analysis of the TiC particles in aluminium containing AlTi3C0.15 grain refiner NAGLIC, I., SMOLEJ, A., DOBERSEK, M. vol. 45 (2007), no. 6, pp. 293 - 298
Abstract Determination of orientation relationships between TiC particles and the surrounding aluminium matrix using transmission electron microscopy is the main objective of this study. The melt of the commercial-purity aluminium and the commercial grain refiner AlTi3C0.15 were used to prepare experimental samples. Two orientation relationships between aluminium and TiC were found:[111]αAl ll [111]TiC and (110)αAl ll (110)TiC, and [114]αAl ll [110]TiC and (110)αAl ll (110)TiC planes of TiC and aluminium were found to be parallel what indicates the epitaxial nucleation of aluminium on {111} planes of TiC.
