Abstract
The invention relates to foundry. A method of thixocasting includes preparation of melt, its processing by a vibro-pulse activator in the temperature range of precrystallization state to a temperature of T- 5-, where the T- liquidus temperature of the processed melt, filling φ mold cavity with melt and its crystallization under pressure. The method allows to extend the range of melt processing, and guarantees a greater number both of nuclei and microcrystals, which provides guaranteed casting with a globular structure while reducing energy costs. It also provides for guaranteed obtaining a thixostructure with an average size of α-solid solution globules not more than 55 microns.
