Nanostructured crystallization of casting alloys
Litiyo i Metallurgiya (FOUNDRY PRODUCTION AND METALLURGY), 2022 Crystallization of casting alloys has been shown to be a nanostructured process. Microcrystals of phases in the temperature range of liquidus and solidus, during eutectic and peritectic reactions, are formed from nanocrystals of components A and B of alloys, their free atoms and atomic complexes.
