Abstract

Optical, electron metallography and X-ray diffraction techniques were employed to characterize the microstructure of a rapidly solidified Al-12 wt% Si alloy. Ribbons produced with the planar flow casting process at a cooling rate of 106 Ks−1, had a very fine cellular structure of αAl and nanosize Si particles which are distributed inside and at the boundaries of these cells. Thinner sections (t<30 μm) have apparently experienced higher cooling rates and show, in addition to a cellular structure, a distinct zone which is featureless at optical microscope magnifications.
