| الوصف: | The article proves that important achievements of theoretical developments regarding the use of iron-based alloys are the scientific works of domestic researchers. Thus, in the dissertation research of Karpets M.V. for the first time, the phase composition, microstructure and physicо-mechanical properties of alloys of the Сr-Ni-Co-Fe-Cu-Al system in the concentration range (0-3 mol) of the content of chemical elements were systematically investigated. It was established that in the studied system, due to the high entropy of mixing, only simple solid substitution solutions based on fcc and bcc structures are formed, which are characterized by a high complex of physical and mechanical properties that are not inherent to any of the constituent components. It is substantiated that the main factor of phase formation in high-entropy alloys is the value of the average electron concentration of the alloy. The interval of values of the average electron concentration, in which bcc or fcc structures exist, depends on the rate of crystallization of the melt and the presence of elements prone to liquation in the alloy. Stabilizing elements of solid solutions based on phases with bcc (Al, Cr) and fcc (Cu, Ni, Co) structures were established. A significant scientific achievement should be considered the first developed high-entropy CrMnFeCoNi2Cu alloy based on a solid solution with an fcc phase structure, capable of being deformed by rolling at room temperature by 98% without the appearance of cracks or tears. Its phase composition, microstructure, and physical and mechanical properties at all stages of deformation were studied. It is shown that, for the first time in Ukraine, during cold rolling in the high-entropy CrMnFeCoNi2Cu alloy, similar to pure metals and alloys with an fcc structure, a rolling texture with the main component appears. The article provides examples of other theoretical developments regarding the use of iron-based alloys. ; В статье доказано, что важными достижениями теоретических разработок ... |
