Heating effect of an electron beam impinging on a solid surface, allowing for penetration

J. Vine、P.A. Einstein1964-01-01Proceedings of the Institution of Electrical Engineers

The heating effect of an electron beam, under the assumption that the entire beam energy is imparted to the target surface (disc heating model), can be calculated fairly readily. At the high voltages and small beam diameters employed in electron-beam machining, however, the problem is complicated by penetration of ele…

The transparency of crystalline polymers

Ruth Pritchard1964-01-01Polymer Engineering and Science

Abstract Much past confusion has originated from attempts to describe the complete optical properties of a plastic in terms of a few ill‐defined parameters. Simple light‐scattering theory and studies of morphology have been combined in this article to suggest the causes of polymer opacity; methods cited for the improv…

3—THE GEOMETRICAL PROPERTIES OF SIMPLE WARP-KNIT FABRICS

P. Grosberg1964-01-01Journal of the Textile Institute Transactions

The geometrical properties of 2-bar full-set fabrics are considered in terms of two models; one in which there is a great deal of friction, so that parts of the structure are isolated from each other, and one in which this friction can be neglected. Il is shown that the model with the frictional restraint appears to p…

Elastic Constants of a (73.8% Ni-26.2% Fe) Ferromagnetic Alloy

Norman G. Einspruch、L.T. Claiborne1964-01-01Journal of Applied Physics

The elastic constants of a (73.8% Ni-26.2% Fe) ferromagnetic alloy have been measured at 300°K with the following results: C11=23.04, C12=14.44, and C44=11.92 (in units of 1011 dyn cm−2). These results are compared with previously reported work on pure Ni and a (30% Ni-70% Fe) alloy.

Plasma Anodized Aluminum Oxide Films

George J. Tibol、Robert W. Hull1964-01-01Journal of The Electrochemical Society

A low‐pressure gas plasma of oxygen ions has been used as the electrolyte for anodizing evaporated aluminum films on glass substrates. The oxide film grows at 22Aå/v at low voltages, while above 50v, the growth rate is somewhat less. Films have been anodized up to 90v. Capacitors formed of such plasma anodized aluminu…

Analysis of the Hydrogen Reduction of Silicon Tetrachloride Process on the Basis of a Quasi-Equilibrium Model

T. O. Sedgwick1964-01-01Journal of The Electrochemical Society

The process for the growth of silicon single crystals by the hydrogen reduction of silicon tetrachloride has been described using a model which assumes that chemical equilibrium obtains at the silicon deposition site. The thermodynamic calculations by Lever for the equilibrium gas phase composition in the Si‐Cl‐H syst…

The Role of Hydrolysis in the Reaction of Heavy Metals with Soil‐Forming Materials

J. F. Hodgson、K. G. Tiller、Martha Fellows1964-01-01Soil Science Society of America Journal

Abstract The proposition that hydrolysis may account for the selective adsorption of heavy metals by clay surfaces is compared with an alternate explanation of specific exchange of the metal with weakly dissociable H + . It is shown that past evidence offered in support of the two hypotheses is somewhat ambiguous. The…

Surface Activity at Organic Liquid-Air Interfaces

N. L. Jarvis、Robert B. Fox、W. A. Zisman1964-01-01Advances in chemistry series

The present investigation describes the successful modification of the surface properties of polymeric solids by the adsorption of appropriate partially fluorinated compounds at polymer-air interfaces during the formation of the polymer surfaces. The extent of additive adsorption was found to be dependent upon the mol…
