ferrite sind magnetische werkstoffe, die in der technik vielseitige verwendung finden.z.b. ferritantennen, magnetophon, magnetische verstarker, magnetregler informationsspeicher,schaltelemente ; u.s.w. neue typen von ferriten erschlissen sich immer wieder neue anwendungsgebiete. die magnetische eigenschaft der ferrite hangen von der anordnung der atomen in kristallstruktur abo ferrite haben ein...

It has been shown that the elementary crystal cells of basic products deoxidation and modification carbon steel, ? ferrite austenite do not correspond to principle structural dimensional correspondence Dankov – Konobeevsky. Modifying elements Ba, Ca, Mg, Ce, Al increase surface energy iron?carbonaceous melt by binding active oxygen. Deoxidizers combine dissolved (free) oxygen into oxides, modif...

A new technique which allows the simulation of thin ferrite absorbing tiles in a coarse TLM mesh is described. Results are presented which show a good fit to manufacturers' reflectivity curves. Experimental and simulation results for a screened room partially lined with ferrite are presented to demonstrate the accuracy of the method. INTRODUCTION The Transmission Line Matrix (TLM) method of num...

Local electron work function, adhesive force, modulus and deformation of ferrite and austenite phases in a duplex stainless steel were analyzed by scanning force microscopy. It is demonstrated that the austenite has a higher electron work function than the ferrite, corresponding to higher modulus, smaller deformation and larger adhesive force. Relevant first-principles calculations were conduct...

Resonance experiments are described on polycrystalline ferrite spheres in a microwave cavity with a linearly polarized magnetic field. Fundamental quantities, like the g-factor and the damping coefficient 'of the ferrite, are derived from the measurements. The damping coefficient can be calculated either from a linewidth measurement or from the maximum amount of absorption in the ferrite at res...

New developments with bainite have resulted in a steel with an ultimate tensile strength of 2500 MPa, a hardness of 600-670 HV and a toughness in excess of 30-40 MPa m [1]. The novel microstructure is generated in a high carbon (0.98 wt.%) high silicon (1.46 wt.%) steel austenitized for 15 min. at 1000 oC, and then isothermally transformed at temperatures of ∼200 oC. Iron does not diffuse durin...

In this study, in vitro cytotoxicity of nickel zinc (NiZn) ferrite nanoparticles against human colon cancer HT29, breast cancer MCF7, and liver cancer HepG2 cells was examined. The morphology, homogeneity, and elemental composition of NiZn ferrite nanoparticles were investigated by scanning electron microscopy, transmission electron microscopy, and energy dispersive X-ray spectroscopy, respecti...
