Rate and temperature effects on the fracture toughness of a rubber-modified epoxy
(Elsevier, 1993-04)
A series of three-point bend fracture toughness tests was performed at various loading rates and temperatures on both rubber-modified and unmodified epoxy specimens. The fracture toughness of the modified samples was ...
The effect of non-linear diffusion on solid state amorphization in Ni-Hf: experiment and simulation
(Elsevier, 1993-05-07)
Solid state amorphization in the Ni---Hf system has been studied by measuring the reaction rate of terminal solutions with as-prepared amorphous alloys of various compositions. This methodology allows direct determination ...
An Investigation into the Mechanical and Transport Properties of Aqueous Latex Films: A New Hypothesis for the Film-Forming Mechanism of Aqueous Dispersion System
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1993-03)
The effects of plasticizer, physical aging, and film-forming temperature on the mechanical and transport properties of films formed from aqueous dispersions of ethylcellulose latex were investigated. The water vapor ...
Study of fracture mechanisms of multiphase polymers using the double-notch four-point-bending method
(Kluwer Academic Publishers; Chapman & Hall ; Springer Science+Business Media, 1993-01)
The double-notch four-point-bend technique (DN-4PB) is developed to study the fracture mechanisms of multiphase polymers. This technique is found to be effective for an unambiguous determination of the fracture mechanisms ...
Evidence for self-sustained MoSi2 formation during room-temperature high-energy ball milling of elemental powders
(Materials Research Society, 1993)
Ba[Si(OCH 2 CH 2 O) 3 ], a Hexaalkoxysilicate Synthesized from SiO 2 This work was supported by the Air Force Office of Scientific Research. We would like to thank Prof. Linda Nazar, Waterloo, and Prof. Florence Babonneau, Paris, for continuing collaborations, especially for running solid-state NMR studies; and Prof. R. J. P.

The preparation and morphology of PPO–epoxy blends
(Wiley Subscription Services, Inc., A Wiley Company, 1993-05-10)
Poly(phenylene oxide) (PPO) was found to be miscible in diglycidyl ether of bisphenol A (DGEBA) based epoxy. The PPO–DGEBA system exhibited upper critical solution temperature (UCST) behavior. The cloud point temperatures ...
Monte Carlo simulation of phase separation during thin‐film codeposition
(The American Institute of Physics, 1993-08-01)
The results of Monte Carlo simulation of phase separation during binary film coevaporation are presented for a range of deposition conditions. The model employed assumes that phase separation occurs through surface ...
Fibrous Monolithic Ceramics: I, Fabrication, Microstructure, and Indentation Behavior
(Blackwell Publishing Ltd, 1993-09)
Synthesis and properties of microlaminate structures by ion beam assisted deposition
(Elsevier, 1993)
Films of Al, Al2O3, Mo and MoSix were formed by ion beam assisted deposition (IBAD) at R ratios between 0.004 and 0.1 and film thicknesses between 150 and 1100 nm. Al films were crystalline with a strong (111) fiber texture ...
