This article presents the results of investigation of the influence of holding temperature during the quenching process on the microstructure and superplasticity of the Co-Ni-Nb alloy. Temperature-strain rate intervals of the deformation of the superplasticity effects are stated. The optimal regimes of the preliminary treatment by quenching and rolling as well as the routine of the superplastic deformation of the Co-Ni-Nb alloy are defined. The interval of the temperatures of the precipitation, morphology, composition, type and parameters of the lattice of the secondary phase, which appears after the annealing + rolling (to 90%) Co-Ni-Nb alloy, are determined.

The present study investigates samples of Cu-Mo composite material produced through explosive welding. The microhardness of these samples is measured and their structures are analyzed using optical and electron microscopy methods. Copper and molybdenum regions are mapped at the Cu-Mo boundary. The analysis reveals a complex fractal line and dark areas at this boundary, indicating the formation of a new phase. Microhardness measurements indicate that the hardness of both copper and molybdenum increases in comparison to standard values for annealed samples of copper and molybdenum, respectively. Furthermore, the hardness of molybdenum increases at the interface with copper, which may also suggest the formation of a new phase. The electron microscopy analysis and mapping of copper and molybdenum regions at the Cu-Mo interface confirm the presence of a new phase, which is referred to as "forced eutectic." This is because copper and molybdenum do not typically form solid solutions, eutectics, or intermetallic compounds under equilibrium conditions. The new phase exists only under nonequilibrium conditions.

The occurrence of ferromagnetism and an increase in electrical conductivity in beryllium ceramics having the BeTiO3 perovskite structure were experimentally detected. Models to explain the occurrence causes of the discovered metallic properties are proposed. Calculations of the electronic structures of nanoclusters with various short-range orders were carried out.

This article examines the processes of structure formation occurring during joint plastic deformation by the explosion of copper and molybdenum. These components are dissimilar metals with very limited mutual solubility under normal conditions, and the circumstances allowing for their interaction, as well as the products of the mechanochemical reactions of such interactions, have not been sufficiently studied and require new approaches. A cluster approach was used to describe the processes of structure formation, which describes phase formation as the process transitioning of the polyhedron of the initial phase into the polyhedron of the final phase. This work shows that under the conditions under consideration, not only is the formation of solid solutions in the contact zone with smooth concentration transitions from one component to another possible, but also the formation of new structural states, which can be represented as localized icosahedral atomic configurations (amorphous metal clusters). Such a structure is capable of locally strengthening the composite, which is confirmed by microhardness studies.
