Abstract
The tensile properties and fracture behavior of gradient nano-grained/coarse-grained zirconium produced by surface circulation rolling treatment were investigated. Experimental results indicated that gradient nano-grained zirconium foil exhibits high yield strength (â¼748Â MPa) and reduced tensile elongation (â¼3.0%) relative to its coarse-grained counterpart. On the contrary, the gradient nano-grained/coarse-grained zirconium shows good mechanical properties which combine the strengthening from nanocrystalline zirconium with the strain hardening provided by coarse-grained zirconium. Localized plastic deformation is effectively suppressed, instead of a uniform and fish-scale overall deformation.
