34. Structure, physico-chemical, mechanical, and operational characteristics of condensed composite materials of the Cu-Cr system for electric contacts

Author

Grechanyuk, N. I., Grechanyuk, I. N., Osokin, V. A., Kharchenko, V. V., Bukhanovskii, V. V., Rudnitskii, N. P., Vitez, Ivan, and Mamuzić, Ilija

Subjects
Cu-Cr system, electric contacts
Abstract

The structure, electro-physical, chemical, and mechanical characteristics of composite materials of the Cu-Cr system with the content of the components from 0 to 100 mass% were studied. The composites were obtained by the method of electron-beam evaporation of the initial materials with a subsequent joint condensation on a steel substrate and vacuum annealing at 900°C during 3 hrs. Hardness, characteristics of strength and plasticity of the materials were determined in the temperature range from 20 to 800°C in vacuum not lower than 0.1 Pà .

Abstract

The structure, hardness, strength and plasticity of a laminated composite nanomaterial of the copper-zirconium-yttriom– molybdenum system obtained by electron-beam evaporation and layered vapor condensation over a temperature range of 290-1070 K are studied. Correlation between the hardness and strength of the composite was established.

Abstract

The results of experimental investigation on deformation and strength of unidirectional carbonfiber-reinforced plastics made on the basis of carbon fibers T700 and epoxy matrix at room and elevated (up to 260°C) temperatures are presented. The dependences of the elasticity characteristics and strength of the composite on the test temperature are investigated. The metallic characteristics and strength of carbon fibers and matrix at room and elevated temperatures are determined. [ABSTRACT FROM AUTHOR]

50. An Aluminum-Base Antifriction Alloy

Author

FOREIGN TECHNOLOGY DIV WRIGHT-PATTERSON AFB OHIO, Rudnitskii,N. M., Rassadin,Yu. A., Fokin,I. E., Nikolaev,V. V., Kiselev,I. A., FOREIGN TECHNOLOGY DIV WRIGHT-PATTERSON AFB OHIO, Rudnitskii,N. M., Rassadin,Yu. A., Fokin,I. E., Nikolaev,V. V., and Kiselev,I. A.

Abstract

This invention pertains to aluminum-base antifriction alloys used in motor and tractor mechanical engineering. The proposed metal is specifically designed for the manufacture of internal combustion bearing inserts coated with a bread-in coating. Heavily loaded internal combustion engines with a specific pressure up to 600 kg/sq cm impose increased requirements on the strength of the antifriction aluminum alloy. These increased strength features are achieved by selecting an alloy with the following composition, in %: Lead 4-6; tin 1-3; copper 0.5-1; silicon 1.5-2.5; nickel 0.1-4; aluminum remaining.
