METHOD FOR OBTAINING A HEAT-RESISTANT LOW-CARBON IRON-ALUMINUM ALLOY Russian patent published in 2021 - IPC C22C38/06 C22C33/04 

FIELD: metallurgy.

SUBSTANCE: invention relates to the field of metallurgy, in particular to the production of cast low-carbon iron-aluminum alloys for the production of castings. The aluminum-containing part of the charge and the modifying additive are jointly introduced into the melt under the slag layer in an amount of 1-2 capsules, providing the content in the finished alloy, wt.%: aluminum 12.0-16.0, carbon 0.05-0.1 and titanium 0.9-1.2, while granular aluminum or a section of aluminum is used as the aluminum-containing part of the charge, ferrotitanium of the FTi-30 brand is used as a modifying additive, and a mixture containing the oxides SiO₂, CaO, Al₂O₃ and MgO is used as a slag.

EFFECT: invention makes it possible to obtain an alloy with increased heat resistance and a crushed structure, to improve its mechanical properties.
