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

Thermodynamic Assessment of the Co-Mo System

Author(s)
Albert Davydov, Ursula R. Kattner
The experimental thermochemical and phase diagram data for the Co-Mo system were assessed. A consistent thermodynamic description, using a Redlich-Kister model

Metastability and Depletion Driven Aggregation

Author(s)
Erik K. Hobbie
Depletion driven aggregation in binary colloidal mixtures is studied via the time evolution of the cluster-size distribution and structure factor as the
