Investigation of microstructure and local mechanical properties of zirconium alloys
Original language description
Zirconium alloys are very important materials used in nuclear reactors. Due to their high corrosion resistance and low thermal neutron capture cross section are these alloys ideal for production of cladding of the nuclear fuel rods. In order to define their resistance to damage, it is necessary to know their mechanical properties after long-term service and high temperature oxidation, as well as the reasons for changes in those characteristics. This paper presents the evaluation of microstructure, localmechanical properties, results of X-ray diffraction and electron microprobe measurements of the Zr-alloy after various exploation times prior to cooling, which simulated the LOCA (loss of coolant accident) conditions. The microstructure was studied by optical and scanning electron microscopy. The indentation hardness was evaluated by nanoindentation method. The parameters and the volume of the lattice of phases, were analysed by X-ray diffraction method. The chemical composition, primar
