The development of modern mechanical engineering forces us to constantly improve the technology processing materials and look for ways not only quality products but also increase efficiency process itself. This article discusses an alternative method finish product, which can replace traditional grinding, magnetic abrasive treatment. is a solution that allows you obtain high surface processed p...

Optimizing fabrication parameters for rapid solidification of Re-Fe-B (Re = Rare earth) alloys can lead to nanocrystalline products with hard magnetic properties without any heat-treatment. In this work, we enhanced the magnetic properties of Ce17Fe78B₆ ribbons by engineering both the microstructure and volume fraction of the Ce₂Fe14B phase through optimization of the chamber pressure and the w...

This study introduced a method based on magnetic field assisted finishing mechanism for micromachining the inner surfaces of Aluminum tubes. In this approach, using the alternating magnetic field of an AC electromotor, abrasive particles were formed as Magnetic Rods (Magnetic Clusters) and surface micromachining was carried out by the dynamic particular pattern made by an alternating magnetic f...

This study deals with the 3D recovering of magnetic susceptibility model by incorporating the sparsity-based constraints in the inversion algorithm. For this purpose, the area under prospect was divided into a large number of rectangular prisms in a mesh with unknown susceptibilities. Tikhonov cost functions with two sparsity functions were used to recover the smooth parts as well as the sharp ...

This paper deals with the theoretical investigation of the thermal instability of a thin layer of electrically conducting micropolar rotating fluid, heated from below in the presence of uniform vertical magnetic field in porous medium. A dispersion relation is obtained for a flat fluid layer, contained between two free boundaries using a linear stability analysis theory, and normal mode analysi...

The purpose of this study was to examine the correlation between CR (Cosmic Ray) intensity and solar, interplanetary and terrestrial parameters. The hysteresis loops of (CR) versus those of several solar parameters showed narrow loops in even cycles 20, 22 and broad loops in odd cycles 19, 21, as also in the recent odd cycle 23. Hysteresis plots for CR versus interplanetary number density N and...
