Melting Equilibria of the BaF2-CuOx System

Author(s)
Winnie Wong-Ng, Lawrence P. Cook, J Suh
Since the BaF 2-CuO x system is a limiting binary of the overall quaternary reciprocal Ba,Y,Cu//F,O phase diagram, it provides an important frame of reference

Crystal Asymmetry Induces Single-Atom Chain Formation in Gold Nanowires

Author(s)
Francesca Tavazza, A Hasmy, Lyle E. Levine, Anne M. Chaka, Luis C. Rincon, M Marquez, Carlos A. Gonzalez
We performed density functional theory and tight-binding molecular dynamics calculations to investigate the formation of suspended linear atom chains when

On the Existence and Stability of Quadrijunctions

Author(s)
John W. Cahn, E S. Vanleck
The existence and stability of various microstructural features for two-phase materials with anisotropic energies is discussed. In particular, the existence of

Deformation of Heterogeneous Adaptive Composite

Author(s)
Julia Slutsker, Alexander L. Roytburd
The superelastic deformation of an adaptive layer composite containing a shape memory alloy as an active component is considered in this paper. It is shown that

Internal Friction Tensor in Langasite (LA3Ga5SiO14)

Author(s)
H M. Ledbetter, Sudook A. Kim
Using acoustic spectroscopy, we measured the complete elastic-constant and internal-friction tensor C y = C y (1+Q -1 y) of langasite, a trigonal-symmetry

Fracture of Silicate Glasses: Ductile or Brittle?

Author(s)
J -. Guin, Sheldon M. Wiederhorn
Atomic force microscopy is used to investigate the possibility of crack tip cavitation during crack growth in silicate glasses. Matching areas on both surfaces

Clementite's Elastic Constants

Author(s)
Sudook A. Kim, H M. Ledbetter
By extrapolation, we estimated cementite's elastic constants. Altogether, we studied seven Fe-C binary alloys varying from 0 to 17.3 atomic percent carbon. Thus
