Title: Molecular composites via ionic interactions and their deformation/fracture properties

Abstract

Homogeneous molecular composites have been made from ionic PPTA and PVP, in which a good dispersion of rod molecules is achieved via ion-dipole interactions. Appearance of a single T{sub g} as well as morphological observations by TEM have indicated good dispersion of the rigid-rod PPTA molecules. The deformation mode of the matrix polymer is modified significantly with the addition of rod molecules: while crazing is the only deformation mechanism of PVP, an addition of ionic PPTA molecules into the PVP matrix induces shear deformation. This suggests better fracture properties of these molecular composites. Initial studies have indicated significant enhancement in mechanical properties.

  • This paper describes rubbery materials of high ionic conductivity dominated by Li transport prepared by dissolution of polypropylene oxide and polyethylene oxide in low melting molten salt mixtures, with and without plasticizing additives. The dominance of Li{sup +} transport is demonstrated by measurements of anion (I{sup {minus}}) diffusivity which show that anions probably contribute less than 1% of the conductivity. The authors also describe experiments using the wide electrochemical window (>5V) polyanionic material obtained by polymerizing lithium vinyl sulfonate. This polymer can also act as a glass formation promoter in salt mixtures and, like other high molecular weight polymers, canmore » bestow rubbery properties. The authors also report studies of the solution and glass properties.« less
  • A geometrical variant of hybrid composite model and explanation for description of deformation properties are proposed. The main elements of such model are composite rods. The structurogram series of composite elements model and composite as a whole were studied. the numerical and quantitative analysis by means of the Videolab-system give us an opportunity to obtain the morphological characteristics of tense regions distribution and general integral structure description. Structure model geometry of hybrid composite with optimum distribution of tense area was determined under stress and shear. The difference between the experimental data and the results of calculation of the classic deformationmore » properties of composite model is about 5--8%.« less
  • A review is presented of the design of suitable materials systems for joining by high-temperature plastic deformation, details of the joining techniques, microstructures and properties of the resulting composite bodies, and prospects and limitation for this type of joining technology. Joining parameters and resulting forms are discussed for Al{sub 2}O{sub 3}/mullite particulate composites, Y{sub 2}O{sub 3}-stabilized ZrO{sub 2} particulate/Al{sub 2}O{sub 3} particulate and whisker-reinforced composites, hydroxyapatite bioceramics, La{sub 0.85}Sr{sub 0.15}MnO{sub 3} electronic ceramics, MgF{sub 2} optical ceramics, and Ni{sub 3}Al intermetallics. Results are contrasted with those obtained by other methods of joining brittle, high-temperature materials, with special focus on durabilitymore » and mechanical properties.« less
  • The deformation and fracture toughness properties of forged stainless steels pre-charged with tritium were compared to the deformation and fracture toughness properties of the same steels heat treated at 773 K or 873 K and precharged with hydrogen. Forged stainless steels pre-charged with tritium exhibit an aging effect: Fracture toughness values decrease with aging time after precharging because of the increase in concentration of helium from tritium decay. This study shows that forged stainless steels given a prior heat treatment and then pre-charged with hydrogen also exhibit an aging effect: Fracture toughness values decrease with increasing time at temperature. Amore » microstructural analysis showed that the fracture toughness reduction in the heat-treated steels was due to patches of recrystallized grains that form within the forged matrix during the heat treatment. The combination of hydrogen and the patches of recrystallized grains resulted in more deformation twinning. Heavy deformation twinning on multiple slip planes was typical for the hydrogen-charged samples; whereas, in the non-charged samples, less twinning was observed and was generally limited to one slip plane. Similar effects occur in tritium pre-charged steels, but the deformation twinning is brought on by the hardening associated with decay helium bubbles in the microstructure.« less
