MODELING OF MICROSTRUCTURE PARAMETERS OF RAPIDLY SOLIDIFIED METALS
With use of developed algorithm of a self-consistent solution of thermal and kinetic problems the growth kinetics of crystals in thin layers of aluminum cooled on a massive copper substrate were explored. For layers 0.05 to 50 μm thick the most probable sizes of crystals and their total volume density number in a unit volume were calculated. The relations between the structural parameters of rapidly cooled foils and the melt cooling rate have been obtained which agree with the literature data.
