Кл.слова (ненормированные):
АЛЮМИНИЕВО-ТИТАНОВАЯ ЛИГАТУРА -- ЧАСТИЦЫ АЛЮМИНИДА ТИТАНА -- ОТЛИВКИ ИЗ АЛЮМИНИЕВЫХ СПЛАВОВ -- ALUMINUM-TITANIUM MASTER ALLOY -- TITANIUM ALUMINIDE PARTICLES -- FOUNDRY GOODS OF ALUMINUM ALLOYS
Аннотация: The metal products of machine-building profile manufactured of billets passed through the cycle of melting-crystallization and having microcrystalline structure, demonstrate higher physical-mechanical properties and exploitation characteristics in comparison with the metal products of macro crystalline structure. During the process of melting the refining structure additives are introduced into liquid metal using master alloys for the aim of the structure refinement. In particular, the similar master alloy is the rod aluminum-titanium master alloy containing titanium aluminide particles which are the crystallization centers. It is determined, that the rod heating in the process of its introducing into the liquid metal leads to enlargement of the titanium aluminide particles, that decreases the efficiency of structure refinement. Therefore, in every particular case, it is necessary to optimize the velocity of rod introducing into liquid metal.
