摘要： A zirconium-base alloy structural member, wherein at least one element selected from phosphours, vanadium, niobium, tantalum, arsenic, antimony, bismuth, sulfur, chromium, molybdenum, tungsten, selenium, tellurium and polonium is distributed on a surface of said member, particularly to a fuel covering tube or spacer for nuclear fuel assembly which is contained the element in a surface oxide layer. The final cold-rolled fuel covering tube is produced by the steps of annealing and coating with the element in the surface oxide layer. The spacer is produced by a step of coating with the element in the surface oxide layer. A process for preparation of a zirconium-base alloy structural member includes, in addition to subjecting a zirconium-base alloy to a final plastic working step, a step of coating its surface with the element. There can be obtained a zirconium-base alloy structural member exhibiting a high corrosion resistance and having a high ductility.

摘要： A zirconium-based alloy with a high corrosion resistance, consisting essentially of 1 to 2wt% Sn, 0.20 to 0.35wt% Fe, 0.03 to 0.16wt% Ni and the balance substantially Zr. The Fe/Ni content ratio of the alloy ranges between 1.4 and 8. The structure of the alloy has a fine intermetallic compound of Sn and Ni precipitated within the zirconium crystal grain of a-phase. The alloy may further contain 0.05 to 0.15wt% Cr. This alloy exhibits reduced hydrogen absorption rate and suffers from no nodular corrosion, so that it can suitably be used as a material of nuclear fuel cladding tubes (1). The nuclear fuel cladding tube (1) made of this alloy exhibits extended service life when used in a nuclear reactor of high degree of burn-up.
