An Investigation for Fracture Toughness and Creep Behavior in Carbon Doped Nanocrystalline Nickel

Abstract

Electrodeposited nanocrystalline nickel that exhibits extraordinary high strength would be a promising candidate for a structural material. The potential engineering applications of nanocrystalline materials need more detailed study on deformation and fracture toughness at room and elevated temperatures under tensile loading. Fracture toughness and creep deformation of nanocrystalline Ni, Ni-C, and Ni-B studied under the course of this research. The results have been published in four (4) papers in refereed journals and have been presented in several international symposiums. One additional manuscript has been submitted recently for publication. Tensile behavior and fracture in nickel and carbon doped nanocrystalline nickel, Creep behavior of nanocrystalline nickel at 290 and 373 K, Creep in boron-doped nanocrystalline nickel, R-Curve characterization of the fracture toughness of nanocrystalline nickel thin sheets, Effect of interstitials on tensile strength and creep in nanostructured Ni.
