T.E.M. investigations of room temperature microplasticity in MgAl2O 4 spinel
نویسنده
چکیده
2014 Dislocations produced by room temperature Vickers indentation on a single crystal of MgO.1.1 Al2O3 spinel have been characterized by T.E.M. These dislocations belong to 1/2 110 > { 111 } glide systems. No trace of { 100 } nor { 110 } glide is found. Moreover these dislocations show no preferred orientation nor visible dissociation. However after annealing for 1 day at 1 000 °C, dissociations of the order of 100 Å are observed.

TEM INVESTIGATIONS OF WC-Co ALLOYS AFTER CREEP EXPERIMENTS
Carbide tungsten cobalt alloys were deformed in compression or in three point bending in a temperature range 1000-1350°C and in a stress domain 30-1000MPa. In these conditions, the stress exponent n of WC-CO alloys is a function of only the cobalt volurnic ratio and tends tow rds n = 1 for pure B carbide. The apparent activation energy is 550 kj mole. T.E.M. investigations on pure carbide defor...
متن کاملMagnetic and Structural Investigations of Nanocrystalline Cobalt-Ferrite
Cobalt ferrite is an important magnetic material due to their large magneto-crystalline anisotropy, high cohercivity, moderate saturation magnetization and chemical stability.In this study, cobalt ferrites Nanoparticles have been synthesized by the co-precipitation method and a new microemulsion route. We examined the cation occupancy in the spinel structure based on the “Rietveld with energies...

Superparamagnetic single phase zinc ferrite nanoparticles have been prepared by coprecipitation method at 20 °C without any subsequent calcination. The composition, crystallite size, microstructure and magnetic properties of the prepared nanoparticles were investigated using X-ray diffraction (XRD), field emission scanning electron microscope (FESEM), transmission electron microscope (TEM)...

In this paper, the mer-Co(NH3)3(NO2)3 complex was used as a new precursor for synthesizing spinel-type cobalt oxide nanoparticles (Co3O4NPs).Thermal decomposition of the complex at low temperature (175 °C) resulted in the Co3O4NPs without using expensive and toxic solvents or complicated equipment. XRD, FT-IR, SEM, EDX, and TEM were employed to characterize the product, and its optical and magn...
متن کاملMössbauer and magnetic studies of surfactant mediated Ca-Mg doped ferrihydrite nanoparticles.
Ultrafine (2-5 nm) particles of amorphous Ca-Mg co-doped ferrihydrite have been synthesized by surfactant mediated co-precipitation method. The evolution of the amorphous ferrihydrite by Ca-Mg co-doping is quite different from our earlier investigations on individual doping of Ca and Mg. Amorphous phase of ferrihydrite for the present study has been confirmed by X-ray diffraction (XRD) and Möss...
