CHROME-BASE INTERMETALLIDE ALLOY

摘要

FIELD: nonferrous metallurgy. SUBSTANCE: chrome-base alloy containing, wt. -%: titanium 18-23 and silicon 1-4 has additionally at least one element of the group involving yttrium 0.2-1 and aluminium 0.2-2 and at least one element of the group involving iron 0.2-2 and nickel 0.2-2. The proposed alloys are biphase ones (alloyed intermetallide CrTi and chrome-base solid solution). Properties: enhanced heat-resistance (overweight is about 1 g/mx h at air oxidation at 1150 C), plasticity (K= 10-12 MPa x m) at sufficient high strength at the increased temperature. Alloy is used for making articles working at 1100-1300 C in oxidative gaseous media. EFFECT: enhanced quality and property of alloy.
