Abstract

The atomic structure of a symmetric 27 degree[001] tilt grain boundary in magnesium oxide has been determined by high-resolution Z-contrast imaging using a 300kV VG HB603U scanning transmission electron microscope with a 1.3 A probe. The atomic configuration in the grain boundary core is found to be considerably less open than the structures proposed for similar materials.

Investigation of Copper Segregation to the S5(310)/[001] Symmetric Tilt Grain Boundary (STGB) in Aluminum

Conference Plitzko, J; Campbell, G; King, W; ...

The {Sigma}5 (310)/[001] symmetric tilt grain boundary (STGB) in the face centered cubic (FCC) metal aluminum with 1at% copper has been studied. The model grain boundary has been fabricated by ultra-high vacuum diffusion bonding of alloy single crystals. The segregation of the copper has been encouraged by annealing the sample after bonding at 200 C. TEM samples of this FCC-material were prepared with a new low voltage ion mill under very low angles. The atomic structure of the {Sigma}5 (310)/[001] STGB for this system was modeled with electronic structure calculations. These theoretical calculations of this interface structure indicate that themore »« less

Atomic structure of a 6[degree][001]/(110) tilt grain boundary in aluminum by HREM

Journal Article Shamsuzzoha, M; Deymier, P; Smith, D - Scripta Metallurgica et Materialia; (United States)

A knowledge of the atomic structure of grain boundaries is central to a better understanding of the properties of polycrystalline materials. Attempts to predict grain boundary structure have so far led to the development of various geometrical models for grain boundaries. The concepts of coincident site lattice (CSL) (1), displacement shift complete (DSC) lattice (2,3,4) and the 0-lattice model (2), based on geometrical constructions of adjoining crystals forming boundaries, have been found useful in characterizing the structure of ideal grain boundaries. These models give suggestions regarding the atomic relaxation that occurs at the core of the boundary in the formmore »« less

Atomic structure of the {Sigma}5 (310)/[001] symmetric tilt grain boundary in molybdenum

Journal Article Campbell, G; Belak, J; Moriarty, J - Acta Materialia

Atomistic simulations offer an important route towards understanding and modeling materials behavior. Incorporating the essential physics into the models of interatomic interactions is increasingly difficult as materials with more complex electronic structures than f.c.c. transition metals are addressed. For b.c.c. metals, interatomic potentials have been developed that incorporate angularly dependent interactions to accommodate the physics of partially filled d-bands. A good test of these new models is to predict the structure of crystal defects and compare them with experimentally observed defect structures. To that end, the {Sigma}5 (310)/[001] symmetric tilt grain boundary in Mo has been fabricated and characterized bymore »« less

Quantitative HREM study of the atomic structure of the {summation}(310)/[001] symmetric tilt grain boundary in Nb

Conference King, W; Campbell, G

We have used a non-linear least squares optimization method to deduce a model for the atomic structure of the {Sigma}(310)/[001] symmetric tilt grain boundary in Nb from high resolution electron micrographs (HREM) of a bicrystal prepared by diffusion bonding. The resultant model is similar to, but differs in detail from a theoretical prediction based on interatomic potentials which included angular forces thought to be important in the prediction of defect structures in body centered cubic metals. Results validate this approach as a step towards making HREM quantitative technique.
