Abstract Die bei 709°C durch peritektische Reaktion gebildete Hochtemperaturphase hat die Zusammensetzung Cu 9,5 As 4 , sie kristallisiert kubisch mit einer Formeleinheit im Elementarkörper. Bei langsamem Abkühlen zerfällt die Hochtemperaturphase peritektoid zwischen 360 und 340°C in β‐Cu 3 As und As. Durch Abschrecke…
Abstract Phase relationships of isotactic polypropylene in various organic diluents were investigated. The diluents used were aliphatic alcohols, alkyl phenols, aryl phenols, diphenyl derivatives, alkyl aryl ethers, esters, and others. Among the diluents examined, n ‐butyl alcohol, p‐tert ‐butyl phenol, p‐tert ‐amyl p…
An experimental study of the TiCo/TiCo+Ti2Co and TiCo/TiCo+TiCo2 phase boundaries has been carried out using high-temperature x-ray diffractometry. The results, together with the result of an approximate mp determination, have been used to delineate the TiCo phase field. By combining this information with the results…
Abstract An idealized polymer model is used to examine the magnitude of the catastrophic tensile breaking energy and stress in terms of primary and secondary bonding forces. Computed strengths for primary and secondary bonding are respectively 8000 and 500 times larger than observed values of a common thermoplastic. F…
The various discharge phenomena caused by contamination of insulator surfaces were investigated by means of slow and fast oscillographic recordings of the discharge current. It was found that the surface discharges have distinct stages of development. The visual manifestations were recorded simultaneously with the cur…

In any attempt to interpret broadened X-ray diffraction peaks in terms of imperfections in polycrystalline specimens, particular attention should be paid to experimental technique and the method of collecting data. The experimental conditions should be arranged to give maximum intensity in as short a time as possible,…
An expression is derived for the strength of the blended yarn spun at optimum twist, in terms of the strengths of yarns spun from the two components at optimum twist. Good agreement between the predicted and observed values is found over a range of cottons and counts. The strength deficiency of the blended yarn is par…

The Mössbauer spectrum of FeAl 2 O 4 consists of three absorption peaks at 0, 1.46 and 2.56 mm s -1 relative to a 57 Co/Cu source. The spectrum can be resolved into two quadrupole-split spectra. The outer pair of lines corresponds to a quadrupole splitting of 2.76±0.10 mm s -1 and an isomer shift of 1.52±0.10 mm s -1…

Deuterated hydrogrossular, Ca3Al2(O4D4)3, has been prepared in order to investigate, by neutron and x-ray diffraction, the isomorphic substitution of (O4H4)4− for (SiO4)4 −. A polycrystalline specimen yielded the cubic-cell edge, 12.5755 ± 0.0009 Å (28°C) and oxygen parameters x = 0.0303(3); y = 0.0547(4); z = 0.6430(…
The crystal structure of interstitial solid solution of zirconium-oxygen system was investigated by means of X-ray, electron and neutron diffraction on specimens in the composition range between 11 and 27 at% O. The specimens were prepared by melting appropriate mixtures of zirconium metal and zirconium dioxide in an…
The nature of the extensional response of anisotropic cylinders, such as helical-wound composite tubes, under various end con ditions is investigated analytically and experimentally. Of particular interest is the existence of a uniform state of stress under practical testing conditions. Also considered is the influenc…

Through an investigation of the transport and related thermodynamic properties of TiNi at and around its ``martensitic'' transition temperature, the existence of a critical range extending over a 60°C interval is established. Within this critical range, the phase transition is second order. Irreversibility of various…
