Abstract:

The influence of the modes of thermal-and-temporal treatment and cooling rate of metallic alloys on crystallization regularities of Al-Sc alloys and their structure, properties, and modifying ability are established. Castings of Al-Sc alloy, which were prepared by the electrolysis of salt melts KF-NaF-AlF3-Sc2O3 at 820-850 degrees C, are used as the initial charge for casting. It is established that, by varying the magnitude of melt overheating and casting temperature, it is possible to vary the crystal shape, amount, and size in wide limits. The modifying action of cast and rapidly quenched master alloys, as well as the master alloy produced by electrolysis, is tested for Al-4.5\% Cu alloy. The largest effect of milling the structure of the Al-4.5\% Cu-0.4\% Sc alloy is attained when using the rapidly quenched master alloy.
