Theoretical analysis has been carried out to establish the heat transport phenomenon of six different ferromagnetic MnZnFe2O4-C2H6O2 (manganese zinc ferrite-ethylene glycol), NiZnFe2O4-C2H6O2 (Nickel zinc ferrite-ethylene glycol), Fe2O4-C2H6O2 (magnetite ferrite-ethylene glycol), NiZnFe2O4-H2O (Nickel zinc ferrite-water), MnZnFe2O4-H2O (manganese zinc ferrite-water), and Fe2O4-H2O (magnetite fe...
The concept of a cyclotron-resonance maser (CRM) with a ferrite loading incorporated in its waveguide is proposed. The CRM interaction occurs between the rotating electron beam and the em wave propagating along a longitudinally magnetized ferrite medium. The ferrite anisotropic permeability resembles the CRM susceptibility in many aspects, and particularly in their similar response to the axial...
Microstructure and behavior of parts fabricated via additive manufacturing (AM) usually differ from their conventionally manufactured counterparts. In an effort to further study such differences, this paper is concerned with comparing weldability characteristics AM wrought materials, for integration replacement into legacy systems. A Gleeble 1500 was used simulate the heat affected zone (HAZ) g...
$ delta $ مجتمع سادکی محض از بعد $(m-1) $ روی مجموعه راس $[n] $ باشد. $ j_{delta} $ ایدآل تولید شده توسط کهاد های $ [a_{1}...a_{m}] $ از ماتریس ژنریک $x=(x_{ij}) $، به ازای $ (1leq i leq m , 1leq jleq n) $ است،که در آن $ {a_{1},...,a_{m}} $ یک فاسیت از $ delta $ است. این ایدآل را ایدآل فاسیتی دترمینانی گویند. در این پایان نامه ایدآل فاسیتی دترمینانی را مطالعه می ک...
We report the synthesis and characterization of ferrite nanocrystals which exhibit high crystallinity and narrow size distributions. The three types of samples including Zn ferrite, Mn ferrite, and Mn-Zn ferrite were prepared via a non-aqueous nanoemulsion method. The structural, chemical, and magnetic properties of the nanocrystals are analyzed by transmission electron microscopy, X-ray diffra...
Spinel copper ferrite (CuFe2O4) and zinc ferrite (ZnFe2O4) nanoparticles were synthesized using a sol-gel self-combustion technique. The structural, functional, morphological and magnetic properties of the samples were investigated by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Transmission electron microscopy (TEM) and vibrating sample magnetometry (VSM). XRD patte...
The mechanical properties, the creep response and the microstructural features of P91 steel have been extensively investigated in recent years since this steel and its derivatives have been used for the production of pipes and tubes. Nevertheless, in plant experience on rolling facilities, showed that the formability of different heats of similar composition can be dramatically different. The o...
A steel has recently been designed to benefit from the deformation induced transformation of retained austenite present in association with bainitic ferrite. It has as its major microstructural component, dendrites of d-ferrite introduced during solidification. The d-ferrite replaces the allotriomorphic ferrite present in conventional alloys of this kind. The authors examine here the stability ...
