Features of formation of structure and properties of Zr-1Nb alloy when manufacturing fuel element shell tubes
Keywords:zirconium alloy, ingot, tubes, fuel element shell, microstructure, special grain boundaries, properties
Structure and properties of cast and hot-worked Zr-1Nb alloy and pilot batches of fuel element shell tubes for water-moderated water-cooled reactors (WWER 1000) of nuclear power plants manufactured from this alloy have been studied. It is shown that satisfactory processing ductility of hot-worked rolled tubes is formed during high-temperature extrusion at a high reduction rate. Presence of special grain boundaries in martensitic structures of Zr-1Nb alloy with a hexagonal close-packed lattice has been established for the first time in the theory of lattices of coinciding nodes. The fuel element shell tubes manufactured according to the developed technology are equal to foreign counterparts in terms of their basic quality characteristics
