STRUCTURAL RADIATION-PROTECTIVE ALUMINUM ALLOY Russian patent published in 2025 - IPC C22C21/06 G21F1/08 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy, in particular to production of aluminium alloys using liquid-phase technologies, in which neutron-absorbing and gamma-scattering elements in form of alloying complexes or intermetallic particles of different dispersion. Structural radiation-protective aluminium alloy, wt.%: boron 1.5–10.0, hafnium 0.4–4.0, magnesium 1.0–7.0, scandium 0.1–1.5, silicon less than 2.0, iron less than 0.5, gadolinium and/or tungsten with total content from 1.5 to 15.0, wherein the gadolinium content does not exceed 12, and the tungsten content does not exceed 10, zirconium or titanium from 1.5 to 5.0, copper or manganese from 0.05 to 5.0, one element from the group containing cerium, lanthanum, yttrium, erbium, ytterbium, dysprosium, europium, lutetium and thulium, from 0.003 to 0.75 and aluminium - the rest.

EFFECT: provided is high ability to absorb low-energy neutrons and gamma radiation (secondary as a result of exposure to neutron fluxes and primary from external sources) at level of mechanical properties not lower than widely used thermally unhardened structural aluminium-magnesium alloys.
