Deformation of electrodeposited nanocrystalline nickel
The mechanisms of deformation and damage evolution in electrodeposited, fully dense, nanocrystalline Ni with an average grain size of ~30 nm and a narrow grain size distribution were investigated by recourse to (i) tensile tests performed in situ in the transmission electron microscope and (ii) microscopic observations made at high resolution following ex situ deformation induced by compression...
متن کاملGrain boundary-mediated plasticity in nanocrystalline nickel.
The plastic behavior of crystalline materials is mainly controlled by the nucleation and motion of lattice dislocations. We report in situ dynamic transmission electron microscope observations of nanocrystalline nickel films with an average grain size of about 10 nanometers, which show that grain boundary-mediated processes have become a prominent deformation mode. Additionally, trapped lattice...
متن کاملComment on "Grain boundary-mediated plasticity in nanocrystalline nickel".
Nanograin rotation via grain boundary sliding has been predicted as an important deformation mode in nanocrystalline materials as grain sizes approach less than 10 nm (1–3). However, definite experimental evidence beyond molecular dynamics (MD) simulations has been long sought. Recently, Shan et al. (4) reported in situ straining dark-field transmission electron microscope (DFTEM) observations ...
متن کاملElectrical resistivity of ferromagnetic nickel and iron based alloys
We discuss in detail the theoretical basis for the two-band model with spinmixing which has been widely applied to the analysis of the transport properties of ferromagnetic metals. This model is shown to have much more general validity than the original presentation suggested. The model is then applied to resistivity data in Ni and Fe based alloys to obtain a consistent set of parameters for th...
