Flashover mechanism of polluted insulation
When a leakage current flows over the wet polluted surface of an insulator, high-resistance dry bands form. Discharges across these dry bands usually become extinguished but, exceptionally, may develop into a flashover of the insulator. The formation of dry bands and the subsequent growth of discharges on the polluted…
Théorie dynamique de la diffraction des rayons X par les cristaux déformés
La théorie dynamique classique de la diffraction des rayons X est étendue au cas des cristaux ayant subi une déformation quelconque et des ondes non planes. La méthode consiste à résoudre les équations de Maxwell en considérant les déformations et la courbure des ondes comme des perturbations du premier ordre. On obti…

Structures of UO2, UO2+x andU4O9 by neutron diffraction
Single crystals have been examined by neutron diffraction in the range of temperatures 20 °C to 1 100 °C and of compositions UO2 to U4O9. The investigations divide into three groups, relating to UO2, UO2+x (where 0 < x < 0.25) and U4O9. UO2 has the fluorite structure at room temperature, with isotropic Debye-Waller fa…
Plastic Deformation and Work‐Hardening in NaCl
Abstract Single crystals of NaCl were compressed at room temperature. The stress‐strain curve shows three well‐defined stages similar to those found for fcc. metals. The dislocation density, bulk density, and deformation characteristics were studied as functions of stress and strain. The recovery of the dislocation de…

The Kinetics of Anodic Oxidation of Iron in Neutral Solution
Iron was anodically oxidized under both potentiostatic and galvanostatic conditions. It was found that the rate of film growth could be expressed by the over‐all equation where Q T is the film thickness, E the potential, and κ', β, and B are constants. A model is proposed based on a "place‐ exchange" mechanism in whic…
Neutron diffraction study on manganese telluride
A neutron diffraction study of manganese telluride has been made using powder specimen. The specimen has been carefully checked by high temperature X-ray analysis and has been proved to be free from MnO and MnTe2 which are apt to contaminate the specimen. This investigation has shown that the magnetic structure of MnT…
Development of the Electrochemical Theory Of Metallic Corrosion
Author explains in detail the kinetics of corrosion processes and gives a thorough study of their thermodynamical problems. He points out the factors which have influence on electrochemical corrosion. He investigates the role of cathodic inclusions concerning corrosion process in alloys and at the same time emphasizes…
Ferrimagnetic spiral configurations in cobalt chromite
Cobalt chromite, CoCr2O4, is a cubic spinel which is ferrimagnetic at low temperatures with a Curie point Tc ≈ 97 °K. The room temperature powder diffraction pattern on this material, corrected for temperature effects, shows that it is a normal spinel with an oxygen parameter equal to 0.38707 :f: .00005. At 4.2 °K the…
SOME ELEMENTARY PRINCIPLES OF POLYCRYSTALLINE MICROSTRUCTURE
This review is mostly concerned with the structure of inorganic polycrystalline materials on a scale much larger than the atom, but dependent upon the behaviour of atoms as its units. Our interest is chiefly in the shape of crystals, but there are two basically different types. There are those, of almost any shape, wh…
Dislocation distributions in deformed copper single crystals
Dislocation etch pit distributions and slip lines were studied on copper single crystals oriented for single glide and deformed in tension at 4·2°K. Slip lines on the cross slip plane were observed from the earliest stages of deformation and their character changed during the transition to stage II. The distribution o…
On the Nonbasal Slip in Magnesium Crystals
In order to determine the characteristics and controlling mechanisms of the nonbasal slip which is the secondary slip system of several hcp metals such as magnesium, tensile tests were performed on single crystals of high purity magnesium having a special orientation whose tensile axis is parallel to the (0001) basal…
Cut growth and fatigue of rubbers. I. The relationship between cut growth and fatigue
Abstract The relationship between the cut growth and fatigue failure of natural rubber vulcanizates under repeated loading is examined. The cut growth behavior has been investigated using several types of test piece, and the results are shown to be consistent when interpreted in terms of the tearing energy concept dev…

Collapse and Rebound of a Spherical Bubble in Water
Some numerical solutions are presented which describe the flow in the vicinity of a collapsing spherical bubble in water. The bubble is assumed to contain a small amount of gas and the solutions are taken beyond the point where the bubble reaches its minimum radius up to the stage where a pressure wave forms which pro…
