ALUMINUM-BASE ALLOY AND ARTICLE MADE OF THEREOF Russian patent published in 2003 - IPC

FIELD: metallurgy of aluminum alloys. SUBSTANCE: invention proposes alloy and article made of thereof that comprise the following component, wt. -%: silicon, 9.5-12.0; manganese, 0.1-0.3; titanium, 0.08-0.1; zirconium, 0.08-0.15; scandium, 0.2-0.3; neodymium, 0.25-0.4; at least two components of the group: cerium, 0.05-0.1; yttrium, 0.02-0.2; boron, 0.1-0.15; germanium, 0.01-0.2; aluminum, the balance. Invention provides the enhancement of plasticity, impact viscosity, crack-resistance both the alloy and welding joins made of deformed aluminum alloys mad with using this alloy as an addition agent material. Proposed alloys can be used for making articles for marine aviation. Alloy can be used as an addition agent in making articles from deformed aluminum alloy AD37. EFFECT: improved and valuable properties of alloy. 3 cl, 2 tbl, 6 ex
