Abstract
Zr-alloyed nano-sized Al-Si ribbons have been synthesized by means of rapid solidification technique. Bulk specimens have been obtained as well by melt casting in metal molds. X-ray diffraction method has been applied to identify the phase composition and grain size. Microstructure studies of “annealed” and “as-obtained” material have been done, finding out that some phases are nano sized. Hightemperature air oxidation kinetics of bulk alloys and ribbons has been studied. In both cases a parabolic kinetic law has been followed but the velocity coefficient depends on the cooling rate applied during the alloys’ solidification
