Computational study of carbon segregation and diffusion within a nickel grain boundary
Using density functional theory, we study the segregation and diffusion of carbon interstitials at a nickel R3 ð1 1 2Þ tilt grain boundary (GB) as a function of C coverage and Ni magnetic state. We find that segregation is most favorable for a ‘‘checkerboard’’ configuration at a coverage of 1 2 monolayer in both non-magnetic (NM) and ferromagnetic (FM) states, with FM (NM) heats of segregation ...
متن کاملGrain boundary segregation in oxide ceramics
D PR O Abstract The factors which control grain boundary segregation in oxide ceramics are reviewed. These include grain boundary energy, cation–cation interactions, impurity cation size, as well as electrostatic interactions with the grain boundary space charge. In addition, an approach for measuring grain boundary segregation in those materials, as a function of the five macroscopic parameter...
متن کاملGRAIN BOUNDARY SEGREGATION OF B IN Ni
Grain boundary segregation of boron in nickel has been investigated using secondary ion mass spectrometry and FIM-AP techniques. Preliminary results show that segregation is of the equilibrium type which means that boron was concentrated to a few atomic layers at the grain boundaries and that the amount of segregation increased with decreasing annealing temperature.
متن کاملGrain Boundary Segregation in Nanocrystructured Metallic Materials
The aim of this chapter is to shed light on the effects of grain boundary segregation on microstructural evolution in nanostructured metallic materials as well as on their mechanical properties. Several key topics will be covered. First, a brief explanation of mechanical stress-driven grain growth in nanostructured Al, Ni, and Cu thin films will be provided in terms of a deformation mechanism m...
متن کاملApplied Thermodynamics: Grain Boundary Segregation
Chemical composition of interfaces—free surfaces and grain boundaries—is generally described by the Langmuir–McLean segregation isotherm controlled by Gibbs energy of segregation. Various components of the Gibbs energy of segregation, the standard and the excess ones as well as other thermodynamic state functions—enthalpy, entropy and volume—of interfacial segregation are derived and their phys...
