摘要: Abstract: Zirconium and its alloys are widely used in nuclear reactors, both as structural components fuel cladding materials. In increasing the burn-up is an effective means of decreasing cost. Waterside corrosion hydrogen absorption reaction zirconium main factors restricting further improvements to rate. Once chemical composition alloy has been determined, properties will be controlled by processing technique selected. Several that affect nanocrystalline metals, such grain boundary, atomic diffusion phase interface characteristics, among others, discussed. When size metal below 100 nm or ultra-fine range (100–1000 nm), mechanical, physical properties, along with microstructural very different from those metals coarse grains.
