REFRACTORY ALLOY Russian patent published in 2014 - IPC C23C30/00 

FIELD: metallurgy.

SUBSTANCE: refractory alloy contains the following element in wt %: titanium 20-35, vanadium 20-35, niobium 20-35, aluminium 5-15, tantalum 2-10, zirconium 1-15. Magnitude of the alloy formation configuration entropy corresponds to the following ratio: ΔS_mix=R∑Ci·lnC_i≥11.2, where ΔS_mix is configuration entropy, J/(mole·K), R is universal gas constant equal to 8.31 J/(mole·K), C_i is concentration of i^th element, at. %.

EFFECT: better manufacturability, higher plasticity, low density, higher strength.
