ALLOY OF THE Al-Mg SYSTEM WITH HETEROGENEOUS STRUCTURE FOR HIGH-SPEED SUPERPLASTIC MOLDING Russian patent published in 2022 - IPC C22C21/06 

FIELD: metal alloys.

SUBSTANCE: invention relates to the field of aluminum alloys with a micrograin structure, in particular to alloys of the Al-Mg system, which can be used for the manufacture of semi-finished and finished products in various industries by superplastic molding. An alloy with a heterogeneous structure of the Al-Mg system for high-speed superplastic molding contains, wt. %: magnesium 4.5-5.5, zinc 0.1-1.0, cerium 0.6-1.2, iron 0.5-0.9, manganese 0.1-0.7, chromium 0.05-0.2, zirconium 0.10-0.30, scandium 0.05-0.3, impurity elements up to 0.2, aluminum the rest.

EFFECT: invention is aimed at increasing the strength properties of the alloy while maintaining high plasticity characteristics by providing a heterogeneous structure in the resulting semi-finished products with a volume fraction of particles of eutectic origin of 4-6% and a grain size of 3-7 microns.
