ZIRCONIUM-BASE MATERIAL Russian patent published in 1995 - IPC

Abstract RU 2032759 C1

FIELD: metallurgy. SUBSTANCE: zirconium-base material has, wt.-%: niobium 0.5-1.5; tin 0.9-1.5; iron 0.3-0.6; chrome 0.005-0.2; carbon 0.005-0.04; oxygen 0.05-0.15; silicon 0.005-0.15, and zirconium - the rest. Structure of material is metallic matrix strengthened by tin-containing and iron-containing intermetallids with volume content of total intermetallids Zr(Fe, Nb)2+Zr(Fe, Cr, Nb)+(Zr, Nb)3Fe 60% (not less) of total content of iron-containing intermetallids at the distance between of their 0.30 ± 0.09 mcm. Alloy properties: overweight at 350 C, under pressure 168 atm above 3000 g - 50-80 mg/sq. dm, deformation of radiation increase at fluence 5,4·1022cm-2 (E ≥ 0.1 mev), 0.25-0.75%. EFFECT: enhanced quality of material. 2 tbl
