ALUMINIUM-BASE STRUCTURAL, DEFORMABLE, THERMALLY NON-STRENGTHENING ALLOY Russian patent published in 2004 - IPC

Abstract RU 2233345 C1

FIELD: alloy metallurgy.

SUBSTANCE: invention relates to deformable thermally non-strengthening alloys designated for using as deformed semi-finished product as the structural material. Invention proposes alloy comprising the following components, wt.-%: magnesium, 5.0-5.6; titanium, 0.01-0.03; beryllium, 0.0002-0.005; zirconium, 0.05-0.12; scandium, 0.16-0.26; cerium, 0.0002-0.0009; manganese, 0.15-0.5, and group of elements including iron and silicon, 0.05-0.12; aluminum, the balance. The ratio of the content of iron to the content of silicon must 1 or above. Invention provides the development of alloy eliciting higher indices of static strength, failure viscosity and cyclic crack resistance as compared with the known alloy.

EFFECT: improved and enhanced properties of alloy.
