Abstract
The results of experimental studies are given for specific formation of the structure of 1565chM alloy in the zone of intersection of welds. The welds are made using friction stir welding (FSW). It is found that the area where two welds intersect features a decrease in the average grain size from 5.2 to 3.3 μm. The measurements made for the moving force of the tool show that, upon moving from the welding section of 1565 chM alloy to the section of intersection with a preliminarily made weld, this value decreases from 11.75 to 3.8 kN. The metal in the area of intersection of two FSW welds has better strength properties. At the same time, the relative elongation is slightly lower here compared to the metal in the single weld stir zone. The static tensile tests reveal the highest strength properties in samples having longitudinal weld orientation relative to the direction of applying the load. Samples with intersecting welds are about 10–15% less strong.
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.
