Abstract—The acoustic emission signals that arise during the interaction of metal zirconium samples with hydrogen, as well as the changes that occur in hydrogenated samples and are sources of high-amplitude acoustic signals, are studied. Hydrogenation of pieces of compact zirconium iodide ranging in size from 5 to 10 mm, shavings obtained from compact zirconium iodide with a linear particle size from 2 to 3 mm and a thickness of ≈0.2 mm, “coarse” electrolytic zirconium powder with a fraction from 80 to 550 μm, and “fine” electrolytic zirconium powder with a particle size of less than 80 μm is carried out. It is established that the source of high-amplitude acoustic signals in all cases is the cracking of zirconium particles at the macro level, which leads to the formation of extended cracks and fractures on the surface of individual particles, as well as to the grinding of the initial materials. Cracking and grinding are caused by deformation and internal stresses that arise in the samples owing to an increase in the volume of the solid phase during hydrogenation. It is shown for the first time that the atomic ratio [H]/[Zr] in the solid phase corresponding to the maximum amplitude of the acoustic emission signal naturally increases in the series pieces of compact zirconium iodide–shavings of zirconium iodide–"coarse" electrolytic zirconium powder–"fine" electrolytic zirconium powder, which is in good agreement with the results of earlier similar studies carried out on the hydrogenation of titanium metal samples.
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.
