Abstract—The effect of irradiation with pulsed helium ion beams and helium plasma on the structural characteristics and mechanical properties of titanium alloys with the following compositions (wt %): Ti–0.5 Nb–0.5 Mo–3 Zr–3 Al; Ti–1 Nb–1 Mo–3 Zr–3 Al; and Ti–1.5 Nb–1.5 Mo–3 Zr–3 Al was investigated. The irradiation was carried out using a Plasma Focus type device with power flux densities of q = 2 × 108 W/cm2 for helium ions and q = 4 × 107 W/cm2 for helium plasma, with pulse durations of 20–100 ns. Metallographic and X-ray phase analyses were performed and the mechanical properties (ultimate strength, yield strength, and elongation) and microhardness of the alloy samples before and after irradiation were determined. The irradiation caused a slight (less than 10%) decrease in the strength and plasticity indicators of the alloy samples, while the microhardness remained practically unchanged.
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.
