Ozherelkov Dmitry Yurievich

2012 — present: PhD in engineering, researcher at the Catalysis and Processing of Hydrocarbons Laboratory, assistant at the Department of Metals Science and Physics of Strength, NUST MISIS.

2018: PhD in engineering, 05.16.01 “Metals science and heat treatment of metals and alloys”, NUST MISIS.

2012: physics engineer majoring in physics of metals, NUST MISIS.

Main research interests of the scientist include materials and methods of additive manufacturing, mechanical properties of materials, fracture processes, and their description. The main scientific results were obtained in the field of additive technologies and 3D printing of metal-matrix composite materials, mainly based on aluminum:

fundamental research was carried out on the formation of aluminum-matrix 3D composites, the influence of technological factors on their physical and chemical properties, and the relationship between the technological parameters, microstructure, and mechanical characteristics of the final product;

several compositions for 3D printing (Al-Al2O3, AlSiMgCu — Al2O3 / AlN, Al-C systems) obtained by various methods were investigated: mechanical mixing, hydrothermal oxidation, chemical deposition;

samples with improved physical and mechanical characteristics were obtained from experimental compositions using selective laser melting (SLM); the optimal modes of alloying compositions were experimentally selected, the optimal complex of mechanical characteristics was achieved;

the regularities of the phase and granulometric compositions and the effect on the properties of synthesized 3D products were investigated;

the obtained regularities make it possible to predict the characteristics of obtained 3D products and control them using fusion modes; improved mechanical characteristics of composite materials were obtained by studying the laser melting processes and the structure formation of the composites during 3D printing.
