The room-temperature damping of three Fe-18Cr-Ni alloys was determined as a function of vibrational strain amplitude at 80 kHz. The data are consistent with the Granato-Lücke theory of dislocation damping. Values of Lc (distance between minor pins) measured are consistent with those obtained from a thermodynamic analy…

The rate-independent theory of transverse impact of textile fibers is reviewed and cast in a form that provides convenient preliminary guidance to designers of impact-resistant textile structures. It is shown that energy-absorption rate increases monotonically with fiber modulus, but that decreased ductility at high m…

The microstructures which may be obtained in superalloys and titanium alloys as a function of alloy chemistry and heat treatment and the contributions of the various phases to tensile, creep, fatigue, and fracture strength are described. The ways in which thermomechanical forming processes can affect the microstructur…

Abstract Scan electron micrographs (SEMs), are shown of three representative types of Georgia kaolin: ‘soft’, Cretaceous-age clay; ‘hard’, fine-grained clay; and ‘flint kaolin’. Sparta Granite and a thick deposit of its overlying saprolite are taken to serve as examples of probable source rock for Georgia kaolin. SEMs…

If the trophic niche of a kind of organism is a connected region in niche space, then it is possible for trophic niche overlaps to be described in a one-dimensional niche space if and only if the trophic niche overlap graph is an interval graph. An analysis of 30 food webs, using the combinatorial theory of interval g…

Abstract Plastic deformation and crazes were initiated in polycarbonate bars containing a round notch by three‐point bending. Morphological observations revealed that internal crazes are nucleated by a hydrostatic stress component caused by plastic constraint ahead of the fully developed plastic deformation zone. The…

The electrical conduction in the sintered oxides of the systems Bi 2 O 3 ‐ M 2 O 5 ( M = V , Nb , or Ta ) has been investigated by measuring the conductivity and the ion transference number. The face‐centered cubic (fcc) phase in these systems was found to show a high oxide ion conduction, and this highly conductive p…

Observation of a new phenomenon, the reversible change in sign of charge transferred to a polymer upon sequential contacts with a series of metals, is reported. This observation is interpreted using a model which attributes the polymer charges to the occurrence of local intrinsic molecular-ion states. A phenomenologic…

Abstract The formation of collagen fibrils from soluble monomers and aggregates by thermal gelation at neutral pH can be divided into two distinct stages: a nucleation phase and a growth phase. Turbidity studies of the kinetics of the precipitation reaction show that the lag‐phase time or nucleation reaction time, t ′…

The paper reviews the crystallographic, optical, magnetic and transport properties of silver chalcogenides Ag2S and Ag2Se. In the low temperature β-phases, the influence of stoichiometry on the respective magnitude of ionic and electronic conductivities is important. In the disordered high-temperature α-phases, the ch…

A detailed assignment of the infrared and Raman O–H stretching bands of disordered ice Ih and Ic is proposed. It is based on the assumptions that the spectra of disordered ice Ic are closely related to those of ordered ice Ic, and that the spectra of the as yet unrealized ordered ice Ic can be predicted from the spect…

This paper presents a physical description of the action of ZnO varistors, which are complex ceramic bodies of ZnO grains sintered in an oxide flux; their conductivity is very low at low voltage, but becomes high after a certain breakdown voltage is reached. It is found that depletion layers in the ZnO adjacent to the…
