Abstract
A zirconium-based alloy for the components of the active core of nuclear reactors comprises (on a weight percent basis): niobium, 0.5-3.0; iron, 0.005-0.5; oxygen, 0.03-0.2; carbon, 0.001-0.04; silicon, 0.002-0.1; nickel, 0.003-0.02; zirconium being the balance; the alloy structure is characterized by an &agr;-solid solution and the &bgr; Nb-phase particles sized below 0.1 &mgr;m and having the niobium content of from 60 to 95%. The alloy may further comprise particles of intermetallics Zr—Fe—Nb with the Fe/Nb ratio of 0.05-0.2. The alloy structure may also be characterized by an oxygen-hardened &agr;-solid solution and by the &bgr; Nb-phase particles, and may further comprise particles of intermetallics Zr—Fe—Nb sized below 0.3 &mgr;m.
