LOW-DEFORMING QUENCHING OF ALUMINIUM ALLOYS Russian patent published in 2016 - IPC C22F1/04 

FIELD: metallurgy.

SUBSTANCE: claimed process comprises high-temperature heating of aluminium alloy and its transfer to water-based cooling medium. The latter comprises two low-concentration polymers, i.e. high-molecular polyethylenoxide and surfactant. Note here that quenching is executed in the cooling medium additionally including the corrosion inhibitor at the following ratio of components, wt %: high-molecular polyethylenoxide - 0.08-0.15, surfactant - 0.5-2.0, corrosion inhibitor - 0.1-1.0, water making the rest.

EFFECT: higher quality of quenching, no need in further straightening of whatever elements, higher mechanical strength and rust proofing.
