The article shows the ability to control magnetic properties due to modulation of phases in the film with varying temperature of growth. So, at low growth temperatures, a film is formed with an axis of easy magnetization in plane. An increase in temperature leads to a change in the phase composition of the film. It is shown that the presence of even a small component of the magnetization vector in the perpendicular direction leads to the appearance of a thermomagnetic effect of a large magnitude with respect to thermal noise
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 structural-phase state in the zone of localization of plastic deformation of the titanium-aluminum composite subjected to high-speed shock load was studied. A sinusoidal nature of the deformation of the boundary of the composite layers beyond the shear strain band, indicating the localization of plastic deformation waves in the stress concentration zone, is revealed. It is shown that the main phase forming in the zone of localization of plastic deformation is the atomically ordered metastable phase Al 3 Ti, with the structure Pm3m.
