A significant redistribution of elements during crystallization was observed. A two-phase microstructure of the κ-phase in the B2 matrix was found in regions with composition below 37 at.% Al and 0.5 at.% C. A microstructure consisting of the κ-phase and B2 matrix with a limited amount of graphite globules was obtained in the fast-solidified Bridgman sample. An enhanced growth of graphite lathes in the Bridgman crystal was observed at a growth rate of 28 mm h-1. These graphite lathes were oriented parallel to the {100} and {110} planes. The κ-phase precipitates have no orientation relationship with the matrix. Pracoviště Fyzikální ústav Kontakt Kristina Potocká, potocka@fzu.cz, Tel.: 220 318 579 Rok sběru 2011
