Abstract Polypropylene film was biaxially stretched in one step in air at 140°C or 152°C, and the deformation was studied optically. A linear relation held between Δ n ss and v A −½ for v A > 10, at both temperatures, where Δ n ss is the birefringence with respect to the normal to the film and v A is the degree of…

Abstract Soils sampled for laboratory characterization in Pennsylvania were separated into those profiles with fragipans and those without fragipans to determine statistically the soil properties consistently related to fragipan occurrence. Fragipans occurred in the following five parent material groups: aeolium, fluv…

Production of sulphides of iron or of tin inside tinplate cans filled with sulphur-containing foodstuffs may cause stains which, although harmless, are a source of complaint from consumers. The formation of iron sulphide is widelythought to be a conversion by H2S or HS-ions of a preliminary Iron corrosion product. Evi…

Summary The application of classical nucleation theory to the initiation of crystal growth in glasses is discussed. Its application to experimental results obtained for the rate of nucleation in three types of glass, one showing nucleation separately from crystal growth, another showing simultaneous nucleation and gro…

The structure proposed for lead sesquioxide by Byström (1947) is incorrect. The space group found in the present work is P21/a with four Pb2O3 in the unit cell; the unit-cell dimensions are: a = 7.814, b = 5.625, c = 8.466 Å (all ± 0.003 Å); β = 124°48′ ± 5′. The structure has been determined by means of X-ray and neu…

Barium ferrite (Ba.0.6Fe2O3) platelets of approximately\frac{1}{2}\mum diameter and with intrinsic coercive force of about 5000 Oe were crystallized from a glass phase. To study the nature of the defects and their influence on the magnetic properties, the crystailized glass was plastically deformed by applying a press…

Abstract The processes of energy dissipation in polymeric foams are discussed. Theoretical considerations and experimental results show that impact behavior of foams with a rate independent modulus can accurately be predicted by Instron data.

The phenomenon, solid cadmium embrittlement, was identified and studied in the titanium alloys Ti-6Al-4V and Ti-8Al-1Mo-1V using cadmium coated tensile specimens and residual stress specimens. The conditions necessary for this phenomenon were found to be tensile stress and intimate contact between the cadmium and tita…

During measurement of preferred crystallographic orientation with the Schulz x-ray diffraction technique, several factors can cause defocusing. Earlier investigations showed that tilt of the specimen in Φ, the angle between the normal to the sample surface and the normal to the diffracting plane, is the most severe li…

We present a reproducible method of synthesizing tetrabasic lead sulfate (4PbO · PbSO4) which produces discrete elongated crystals approximately 22 microns long. Tetrabasic lead sulfate undergoes anodic conversion to PbO2while maintaining the characteristic morphology of the 4PbO · PbSO4crystals. This results in lead-…

Abstract Gelation of poly(ethylene terephthalate) by heating at 263°–300°C was investigated. Under nitrogen flow, crosslinks were scarcely formed. However in air, degradation and crosslinking were common, and these were accelerated by purging gaseous and sublimable degradation products out of the system with a stream…

Benzotriazole is a specific corrosion inhibitor for copper and copper alloys. It is now widely used in industry to reduce the corrosion of these alloys under both atmospheric and immersed conditions. Corrosion of copper may produce a surface stain or tarnish, pitting of surfaces of pipes or promote pitting of other me…

Eigenphases near a resonance are shown to follow an equation which is a simple generalization of the usual equation for the behavior of the phase shift near a resonance in single-channel scattering. The parameters in the equation are shown to have a simple graphical interpretation.
