TANTALUM-SILICON ALLOY, PRODUCTS CONTAINING IT, AND A METHOD FOR PREPARING ALLOYS Russian patent published in 2004 - IPC

FIELD: metallurgy. SUBSTANCE: silicon-containing tantalum-based alloy has sampling standard deviation of tensile strength in wire about 20.684 MPa for unannealed wire at final diameter and about 13.79 MPa for annealed wire at final diameter. Ta-Si alloy preparation comprises transferring, separately or simultaneously, silicon-containing solid and tantalum- containing solid into liquid state, mixing the liquids to form liquid mixture, and forming solid alloy therefrom. Alloys are used for manufacturing tubes, sheets, bands, wire, and condenser elements. EFFECT: enhanced uniformity of properties of alloys with high tantalum percentage. 42 cl, 3 tbl, 3 ex
