Abstract

The structure and properties of rapidly quenched Co₆₉Fe₄Cr₄Si₁₂B₁₁ alloy are studied in the temperature range from –196 to +50°C. It is shown that the plasticity of the alloy does not decrease with long-term exposure and cryocycling. It is established that in the range of operating temperatures from –90 to +50°C, the relative electrical resistance of the microwire r ~ T, the specific electrical resistance ρ = 1.13–1.14 Ωm mm²/m, the temperature coefficient of resistance α = –6.7 × 10^–5 1/K.

期刊介绍： Inorganic Materials: Applied Research contains translations of research articles devoted to applied aspects of inorganic materials. Best articles are selected from four Russian periodicals: Materialovedenie, Perspektivnye Materialy, Fizika i Khimiya Obrabotki Materialov, and Voprosy Materialovedeniya and translated into English. The journal reports recent achievements in materials science: physical and chemical bases of materials science; effects of synergism in composite materials; computer simulations; creation of new materials (including carbon-based materials and ceramics, semiconductors, superconductors, composite materials, polymers, materials for nuclear engineering, materials for aircraft and space engineering, materials for quantum electronics, materials for electronics and optoelectronics, materials for nuclear and thermonuclear power engineering, radiation-hardened materials, materials for use in medicine, etc.); analytical techniques; structure–property relationships; nanostructures and nanotechnologies; advanced technologies; use of hydrogen in structural materials; and economic and environmental issues. The journal also considers engineering issues of materials processing with plasma, high-gradient crystallization, laser technology, and ultrasonic technology. Currently the journal does not accept direct submissions, but submissions to one of the source journals is possible.
