Effects of microstructural heterogeneity on the mechanical properties of pressed soft magnetic composite bodies

RETRACTED: Magnetic properties of iron-based soft magnetic composites with MgO coating obtained by sol–gel method

“…Phosphate insulation is commonly applied for conventional SMCs such as SOMALOY TM due to routine production and adhesiveness to iron powder [5][6][7][8], but has one shortcoming, the maximum annealing temperature, which is about 500 1C [9,10]. Therefore the stress-relief and reduction of hysteresis loss of phosphated powders cannot be completed at the typical stress-relief temperature for pure iron, which is between 570 and 775 1C [3].…”

High temperature properties of ZnO ceramics studied by the impulse excitation technique

“…A more detailed description of the equipment and the measuring technique can be found in published literature. [18][19][20] …”

“…16,17 IET is a well-recognized technique for the investigation of the high temperature behaviour of elastic modulus and internal friction or damping of various materials. [18][19][20] Information about processes taking place in the different phases of complex materials, such as a varistor ceramics, can be obtained by this technique.…”

Reversible and irreversible DC magnetization processes in the frame of magnetic, thermal and electrical properties of Fe-based composite materials

“…They possess certain very good electromagnetic and mechanical properties e.g. the magnetic and thermal isotropy, extremely low classical losses and relatively low total energy losses at medium and higher frequencies (due to an insulating layer between iron powder particles the eddy currents are minimized), as well as a nearly netshape fabrication process ensuring a low cost mass production, which all makes them able to compete with traditionally used materials such as FeSi steels or soft magnetic ferrites at a similar production cost or even cheaper [1][2][3][4][5]. SMCs are well suited for use in alternating magnetic fields for electromagnetic applications such as cores with three dimensional ferromagnetic behaviour for transformers and electromotors, also as the electromagnetic circuits, sensors, electromagnetic actuation devices, low frequency filters, induction field coils, magnetic seal systems and magnetic field shielding [3][4][5][6][7].…”
