Boudinage

Ernst Cloos1947-08-01Transactions American Geophysical Union

A “Boudin” is a sausage, and boudinage is a sausage structure. The term was coined by Lohest [see “References” at end of paper, 1909] for a peculiar structure in certain sandstone beds in the Bastogne in Belgium. The sandstone beds are segmented and the segments are separated from each other by quartz veins. Each part…

ALUMINA‐SILICA RELATIONSHIP IN GLASS*

Hurd W. Safford、Alexander Silverman1947-07-01Journal of the American Ceramic Society

A bstract Assuming from a consideration of silicate minerals that aluminum should replace silicon in silicates, the authors investigated the system Na 2 O‐CaO‐SiO 2 ‐Al 2 O 3 . Densities and refractive indices have been determined and molecular refractions have been calculated. Partial molecular refractivities of Al 2…

Analysis of Tear Strength

O.B. Hager、Davide Gagliardi、HN Walker1947-07-01Textile Research Journal

An analysis has been made of the factors involved in the A.S.T.M. Trapezoid Tear-Strength Test. The tear strength of a fabric measured by this test is dependent mainly on the extensibility of the threads, the breaking strength of the threads, the effective specimen length, and the number of threads per inch of fabric.…

Properties of Liquids at High Sound Pressure

Harold Briggs、J. B. Johnson、W. P. Mason1947-07-01The Journal of the Acoustical Society of America

When sound of high amplitude is transmitted into a liquid by means of a mechanical driving device, the ultimate limitation to the power that can be transferred is cavitation or breakdown of the liquid under high internal stresses. A study of cavitation has resulted in establishing the following results. Under steady-s…

The relation between chemical composition and paragenesis in the biotite micas of igneous rocks

S. R. Nockolds1947-07-01American Journal of Science

Biotite micas from igneous rocks differ from one another mainly in their contents of SiO <sub>2</sub> , Al <sub>2</sub> O <sub>3</sub> , MgO, total Fe as FeO and, to a less extent, in TiO <sub>2</sub> . The variation in amount of each of these oxides was investigated. It was found that some depend on the nature of min…

Stress Relaxation across Grain Boundaries in Metals

T’ing-Sui Kê1947-07-01Physical Review

In order to elucidate further the concept of relaxation of shear stress across grain boundaries in metals, the temperature dependence of internal friction and rigidity modulus of 99.991 percent aluminum have been measured as a function of frequency of torsional vibration and as a function of grain size of the specimen…

The intermetallic compound phases of the system aluminium-manganese-zinc

G. V. Raynor、D. W. Wakeman、Charles Sykes1947-06-17Proceedings of the Royal Society of London A Mathematical and Physical Sciences

Abstract The system aluminium-manganese-zinc has been examined in the range 0 to 95 % of zinc, and 0 to 3 % of manganese. Attention was directed only to the constitution of the alloys above the solidus. Using micrographic and X-ray methods, and the chemical analysis of crystals separated from slowly cooled alloys, it…

X-ray reflexions from dilute solid solutions

Kun Huang1947-06-17Proceedings of the Royal Society of London A Mathematical and Physical Sciences

Abstract The effect on X-ray reflexion of deviations of the atoms from the ideal lattice sites caused by the presence of randomly distributed foreign atoms in a dilute solid solution is investigated quantitatively. The form of the function used to describe these deviations is suggested by the distortions produced in a…

Contributions to the Theory of Beta-Phase Alloys

Clarence Zener1947-06-15OpenAlex

All alloys of the type of $\ensuremath{\beta}$-brass decrease their concentration range in the disordered state as the temperature is lowered. The original theory of Jones is shown to be inadequate, and the observed variation with temperature of the phase boundaries is shown to follow directly from the assumption that…

Spherical Aberration of Compound Magnetic Lenses

L. Marton、K. Bol1947-06-01Journal of Applied Physics

A reduction of the spherical aberration of strong electron lenses can be achieved by a strong lens as a virtual image former and by a transformation of the image in a real one by means of one or more weak lenses. Calculations are carried out for bell-shaped magnetic fields of the axial field distribution H(z)=H01+(z/a…
