although cu and fe are immiscible under equilibrium conditions, they can form supersaturated solid solutions by mechanical alloying. in this paper, nano-structured of the metastable cu-fe phase containing 10, 15, 20 and 25% wt fe were synthesized by intensive ball milling for 15h, in order to achieve a solid solution of fe in cu. the phase composition, dissolution of the fe atoms into the cu ma...

It is well-known that severe deformation to metals causes a direct grain refinement of the matrix without special heat-treatments due to the mechanism of dynamic continuous recrystallization (DCR). However, the microstructural revolution during severe deformation is seemed to be different depending on the deformation mode, namely the direction of deformation. In general, multi-directional defor...

in this research nickel zinc ferrite nanoparticles with composition of ni1-xznxfe2o4 (where x=0, 0.3, 0.7, 1) were synthesized by a sol-gel method at 600 °c for 5 hours. the structure of nanoparticles was studied using x-ray diffraction pattern. the lattice parameter of ferrite nanoparticles was calculated and indicates lattice constant of nanoparticles depend on zinc concentration. the crystal...

the stabilized zirconia with different cu contents synthesized via sol-gel method. the samples were prepared by hydrolysis and condensation of orgnomatelic sol. after that the result gels were dried at 80 °c and then calcined at various temperatures.  ِ the differential thermal analysis (dta), x-ray diffraction (xrd), field emission scanning electronic microscopy (fesem) and transmission electro...

Magnetic spinel ferrite nanoparticles possess high scientific attention for the researchers attributed to its broad area biomedicine purposes, comprising cancer magnetic hyperthermia and targeted drug delivery. Herein, we report ultrasound irritation assisted sol–gel method Zn0.5Co0.5-xAg2xFe2O4 (x = 0.00, 0.10, 0.20, 0.30) (NPs) synthesis. The Rietveld refinement patterns revealed successful s...

Manganese oxides were synthesized during 40 min at 140 ºC via Microwave-Assisted Hydrothermal (MAH) method and treated different temperatures in order to evaluate the phase evolution using structure refinement (Rietveld method). The samples obtained heat defined by means of thermal analysis (160 ºC, 480 715 870 920 1150 ºC) analyzed X-Ray Diffractometry (XRD), Fluorescence (XRF), Fourier Transf...
