Abstract
The appearance of ZhS6K grade alloy granules, the surface and internal structure, and the chemical composition thereof have been analyzed. It is shown that one can control the formation of a preset state of interfaces (tracks, crystallization cells, hatch block boundaries, grains, phases, and discontinuities such as pores and cracks) through the fractional composition, packing density upon filling, and scanning speed in order to obtain a better material quality. The initial structural state of the samples has been studied. An interrelation between the structure of crystallization cell boundaries, dispersed particles, and the structure of fragments has been established. It is shown that all the studied samples have different structural features at the same power and scanning strategy. The analysis has been performed using the methods of optical metallography and scanning electron microscopy (SEM).
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.
