T. Karaaslan et al., INVESTIGATION OF STRUCTURE, METALLOGRAPHIC AND MICRO-HARDNESS PROPERTIES OF RAPIDLY SOLIDIFIED AL-12WT-PERCENT SI ALLOY BY MELT-SPINNING, Physica scripta. T, 58(2), 1998, pp. 182-184
Al-12wt%Si alloy has been manufactured by chill-casting and melt spinn
ing. The resulting microstructures have been examined by optical micro
scopy. It was found that the microstructure of the ribbons is substant
ially different from that of the chill casting X-ray diffraction (XRD)
patterns were obtained The structure of Al-12wt%Si ribbons for the di
fferent disk speeds were examined. In addition, the micro-hardness of
the chill casting and the ribbons were measured. It was found that the
re is a linear relationship between the micro-hardness of ribbons and
the disk speeds.
