NICKEL-BASED ALLOY CONTAINING SILICON, ALUMINIUM AND CHROMIUM Russian patent published in 2017 - IPC C22C19/05 H01T13/39 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy particularly to nickel-based alloy which may be used as a material for manufacture elements of combustion ignition engines. The nickel-based alloy comprises the following, wt %: Si 1.5-3.0, Al 1.5-3.0, Cr >0.1-3.0, Fe 0.005-0.20, Y 0.01-0.20, one or a number of elements: Hf, Zr, La, Ce, Ti <0.001-0.20, C 0.001-0.10, N 0.0005-0.10, Mn 0.001-0.20, Mg 0.0001-0.08, O 0.0001-0.010, S up to 0.015, Cu up to 0.80, Ni and normal technologically due impurities are the rest.

EFFECT: alloy with high resistance against spark erosion and corrosion where at the same time the values of deformability and weldability are sufficient.
