The SCC susceptibility of sensitized Type 304 stainless steel was studied using slow strain rate tests in 0.01 M NaCl as a function of applied potential at temperatures ranging from 100 to 250 C. Potential-temperature domains in which purely IGSCC, simultaneous IGSCC and TGSCC, and IGSCC accompanied by pitting corrosi…
Abstract Thermal degradation behavior of poly(1,3‐phenylene isophthalamide) and poly(chloro‐2,4‐phenylene isophthalamide) was investigated with the aid of some appropriate model compounds. The pyrolysis products of these materials were identified by gas chromatography (GC), gas chromatography/Fourier transform infrare…

Barium ferrite thin films with perpendicular magnetic anisotropy have been prepared by DC diode sputtering. When a sintered target with appropriate composition was used, c-axis oriented Ba ferrite film was obtained whose easy direction of magnetization was normal to the film plane. Its saturation magnetization Ms, coe…
Abstract Values of ζ, the zeta potential, were determined for 34 different Namontmorillonites by electrophoresis. These values were used in the equations of diffuse double‐layer theory to obtain the corresponding values of σ', the surface charge density at the outer limit of the Stern layer. In addition, data on catio…

The dependences of brightness, emission efficiency η, average electric field EA, conduction current JA, and emission lifetime τ upon the device parameters such as film thickness, substrate temperature during evaporation, and Mn concentration have been systematically investigated in ZnS:Mn thin-film electroluminescent…
A general statistical–mechanical description of the liquid–glass transition as a transition from ergodic to non-ergodic behaviour is presented. The description is based on the concept of the different atomic configurations of a glass. The discontinuities of the thermodynamic derivatives of second order, which characte…
As examples of the best use of the so-called AC calorimetry technique, several results are described from various viewpoints. The behavior of heat capacity at ferroelectric, antiferroelectric and structural phase transitions is surveyed from the standpoint of critical behavior, of jump at first order transition, or of…
Magnetization curves are theoretically calculated for exchange-coupled ferrimagnetic double-layered (ECDL) films, each layer of which has a uniaxial anisotropy with the easy axis perpendicular to the film plane and exhibits a rectangular hysteresis loop. With this model are obtained the conditions for the appearance o…
Abstract The electrical resistivity of peroxide and radiation crosslinked polyethylene/carbon black compounds was studied as a function of black concentration and, temperature in heating/cooling cycles. Different carbon blacks in compounds with polyethylene responded differently, regarding electrical resistivity, to t…
Abstract The title reaction was studied in a stirred‐flow reactor at six temperatures ranging from 228 to 297 K and for pressures near 2 torr. The experiments were performed under O‐atom‐rich conditions, and the HOONO 2 concentration was monitored with a modulated molecular‐beam mass spectrometer. O‐atom concentration…
Abstract Calcium carbonate (CaCO 3 ) was precipitated by equilibrating samples of calcareous soil and noncalcareous soil with a dilute sodium bicarbonate solution at two soil‐to‐solution ratios. Different degrees of supersaturation of the soil solutions prior to precipitation were thus achieved by releasing variable a…
Abstract A poly(vinyl chloride) (PVC) plastisol is a suspension of fine particles of PVC dispersion resin in a plasticizer. The particle size ranges typically from about 15 to 0.2 µm and smaller. The PVC particles in the plastisol consist of the primary particles, which are products of polymerization, and of the agglo…
One of the effects of heavy doping is that the dielectric constant varies with impurity density, and thus with position. The general form of Poisson’s equation is solved numerically for a Gaussian p-n junction using a model for ε(N) which is consistent with the experimental data reported by Castner. The results indica…
After a review of previous work, the authors show their results obtained in the study of the effect of pressure on the magnetization mechanisms of polycrystalline soft ferrites up to 1.5 kbar and in a temperature range from 263°K to 573°K. Three kinds of pressures were applied : hydrostatic pressure, lateral pressure…
Magnetocrystalline anisotropy and magnetostriction were measured for the single crystals of Fe-Si-Al alloys lying near the Sendust composition (85%Fe, 9.6%Si, 5.4%Al). The constants K1, λ100, λ111and λsare plotted in the concentration diagram of the Fe-Si-Al system. It was found that K1= 0 is realized in the region of…

Abstract The partial vapor pressures of Mg(g) over the spinel solid solution system, MgO·nAl2O3(n=1.0, 2.0, and 2.8), have been measured by the mass-spectrometric Knudsen-cell method. In the temperature range from 1850 to 2300 K, the pressures are described by these equations: log[P(Mg,g)over 1.0-spinel/atm]=7.72±0.24…
