Abstract:
In the present work, the computer simulation of hysteresis loops of (Nd1-xPrx)2Fe14B compounds with different Pr contents was performed for a temperature range of 300-5 K. The simulation results suggest that the alloying of Nd2Fe14B with Pr (1) leads to reducing the negative effect of the spin-reorientation phase transition on the residual magnetization of the compound (Nd1-xPrx)2Fe14B, (2) reduces the slope of the demagnetization curve making the hysteresis loop more rectangular, (3) does not have a noticeable effect on the maximum value of the coercive force, shifting its maximum to lower temperatures as the Pr content increases.

Abstract:
The microstructural and phase evolution of the powders at different times of milling and after treatment in the flow of the thermal plasma were studied. The X-Ray Diffraction and Scanning Electron Microscopy studies showed that increasing milling time up to 12 h improves chemical homogeneity of the powders and promotes the formation of B2/β-phase solid solution, while at shorter milling times the powders consist of a highly inhomogeneous layered structure with HPC- and BCC-crystal structures.

Abstract:
In recent years, the application of various additions (hydrides, oxides, intermetallic compounds, etc.) to powder mixtures for manufacturing Nd-Fe-B magnets shows promise as the method that allows one to increase the hysteretic characteristics of the magnets at the expense of realized grain-boundary diffusion and grain-boundary structuring processes. The hysteretic characteristics of sintered Nd-Fe-B magnets are highly sensitive to their microstructure and composition of phases. [..]

Abstract:
Nowadays the technological progress of the railway transport is characterized by high demand for new material and technological solutions throughout the whole construction whilst taking into account the carrying and conducting traction equipment, which is traditionally manufactured from pure materials via continuous casting and die forging. The current renewal works of the railway trunks carried out all over Europe connected with simultaneous expansion generate large amounts of traction scrap in the form of worn-out carrying ropes and overhead contact lines.
