Abstract
In this paper, an algorithm for macrofractographic study of materials is proposed on the basis of analysis and sampling of functions and means of measurement of a digital optical microscope. It consists of a consistent implementation of methods developed in this work for studying the fracture surface of materials in a 3D image using digital image processing and using automatic lens recognition and proximity functions. To evaluate the applicability of developed algorithms, dispersion-strengthened composites with an aluminum matrix with different particle sizes and volume fractions fractured under tension were studied. On the basis of results of research, features were established in the mechanisms of fracture and locations of foci and crack nucleation zones during tensile tests depending on the amount content of solid phase in the structure of dispersion-hardened composite materials obtained using internal oxidation technology.
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.
