Influence of Grain Boundary Specialness Character on Grain Texture and Boundary Texture in Nickel Oxide Scales

Texture Development Dependence on Grain Boundary Properties

The motivation for this work is to explain the development of special textures during recrystallization such as the cube component, {001}<100> in fcc metals. Monte Carlo simulation is used with two different mobility and energy functions. The energy function has little influence on texture development whereas the mobility function has a strong influence. A mobility function with a single broad ...

Sensitivity of Texture Development during Grain Growth to Anisotropy of Grain Boundary Properties

Grain 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...

Five-parameter grain boundary distribution of commercially grain boundary engineered nickel and copper

The five-parameter grain boundary distributions of grain boundary engineered nickel and copper specimens have been analyzed in detail. The relative areas of {111} planes in the entire population did not increase as a result of grain boundary engineering (GBE) and, in the R3-excluded population, decreased after GBE. This decrease occurred because the majority of the newly generated R3 grain boun...

Variance of the Grain Boundary Character Distribution

A method for estimating the variance of the grain boundary character distribution from experimental recovery of the two-point correlation functions is derived. The method is illustrated in 2-D to analyze the variance of “susceptible” boundaries in alloy 304 stainless steel. Comparison of these estimates with results obtained directly from OIM measurements is presented. Introduction When the phe...
