| الوصف: | It is shown that the main modifying intermetallides of primary microcrystals of aluminum alloys do not satisfy the principle of structural and dimensional correspondence. Nonmetallic inclusions and intermetallides cannot be centers of crystallization of metallic melts. These centers are nanostructured formations formed from structure‑forming nanocrystals of crystallizing microcrystals of phases and free atoms of alloy components. Such crystallization centers of metal melts satisfy the principle of structural and dimensional correspondence. The main mechanism of action of casting alloy modifiers is a significant decrease in the concentration of surfactants, which reduce the concentration of crystallization centers of metal melts. |
