CORROSION-RESISTANT AND RESISTANT TO OXIDATION ALLOY BASED ON INTERMETALLIC COMPOUND OF NICKEL ALUMINIDE TYPE

摘要

The corrosion-resistant and oxidation resistant high-temperature alloy increased viscosity at room temperature for directional solidification based intermetallic compound type nikelalyuminida following composition: AI 10-20 atomic%. . .5-8.0 at%; Nb 2-10 at.%; In 0.1-2.0 at.%; N1 rest, the sum of AI, Si, Nb and B is not more than 25 at.%. At least 90 vol.% Of the alloy consists of intermetallic phases M1zA1, NiaSi and NIsNb. 4 z.p.f BACKGROUND yl 1.
