It was found that the pharmaceutical preparation of pentoxifylline, treated with a pulsed magnetic field (PMF), changes the antiaggregatory properties.The pharmaceutical preparation contains the pure substance of pentoxifylline and a number of excipients. To understand the mechanism of changes in the antiaggregatory activity of a pharmaceutical preparation, the goal was to further investigate the effect of PMF parameters on its chemically pure substance.PMF processing was carried out on the «MIU Bio» installation with a single exposure at a field strength in the range (0.48–1.17) 106 A/m at discharge circuit frequencies (8–50) 103 Hz.Experiments have shown that the effect of PMF on the pure substance of pentoxifylline did not cause significant changes in its antiaggregatory activity. This result made it possible to get one step closer to understanding the mechanism of the effect of PMF on a given drug. Apparently, the reason for the change in the biological effectiveness of the pharmaceutical pentoxifylline treated with PMF lies in the effect of impurities, which will be the focus of further research.

Both ausforming and transformation temperature affect the successive bainitic transformation and microstructure. The individual influence of each case is clear, whereas the combined effects are still unknown. Thermomechanical simulation and metallography were used to investigate the combined effects of ausforming and transformation temperature on bainitic transformation and microstructure. The kinetics of isothermal bainitic transformation in non-deformed and deformed materials was analyzed. A lower transformation temperature can lead to more bainite formation without deformation. However, ausforming with small strains can partially compensate for the decrease of bainite amount caused by the decreased undercooling. The larger the applied strain is, the smaller the difference between the final amounts of bainite with different undercooling. Ausforming at a relatively higher temperature is more favorable to the acceleration of subsequent isothermal bainitic transformation. The results in the present work provide reference for optimizing the fabrication technology of medium-carbon nanobainite steels.

Physical Phenomena

The paper presents description of physical phenomena arising during the process of electrodynamic forming by means of axisymetric inductors generating pulse magnetic field. Presented material shows the way for determination of pressures acting on non-ferrous pipe elements with an assumption of magnetic flux variation character in system. The paper describes also stages of energy conversion from electric energy of capacitors discharge into mechanical energy of pressure forming semi-finished product. The knowledge about presented phenomena allow to predict final shape of formed product during free forming by electrodynamic method.
