Calculations Of The Intensity Of X-Ray Diffuse Scattering Produced By Point Defects In Cubic Metals, John W. Flocken, John Hardy
Calculations Of The Intensity Of X-Ray Diffuse Scattering Produced By Point Defects In Cubic Metals, John W. Flocken, John Hardy
John R. Hardy Papers
We have calculated isointensity profiles for the diffuse x-ray scattering associated with certain types of defects in Cu, Al, Na, K, Li, and a theoretical model lattice. These profiles were computed for high-symmetry planes very close to reciprocal-lattice points of the (S, 0,0), (S,S,0), and (S,S,S) type. Both cubic and double-force defects were treated. The calculations were done using a technique presented by Kanzaki for the theoretical model lattice. Kanzaki's general conclusion that cubic defects produce leminiscate profiles and that double-force defects produce ellipsoidal profiles is confirmed for all the material studied. Our profiles for the model lattice agree with …
Asymptotic Lattice Displacements About Point Defects In Cubic Metals, John W. Flocken, John R. Hardy
Asymptotic Lattice Displacements About Point Defects In Cubic Metals, John W. Flocken, John R. Hardy
John R. Hardy Papers
We have calculated the asymptotic displacements (a) about a single vacancy in Al, Na, K, and Li, (b) about a single interstitial Cu atom in a Cu host lattice, and (c) about a unit single double force along a (100) direction in A1 and Cu. These calculations were made using the asymptotic equations of the method of lattice statics which, in its full form, is based on the Fourier transformation of the direct-space force equations between the detect and the host atoms in a large "supercell" of the lattice. Results were also obtained for each of the defect types in …
