Theeffect ofTa205additiveon the electric and magnetic properties of MnZn ferrites with fine grain size was studied Aadding small amounts ofTa205 to the MnZn ferriteincreased electric resistivity, while an excessive addition of Ta205causeddecreasein resistivity without significant grain growth. In asmall amount ofTa205 the change in the electric resistivity can be explained by ~ a ' ' substituti...
متن کاملDislocation Creep: Climb and Glide in the Lattice Continuum
A continuum theory for high temperature creep of polycrystalline solids is developed. It includes the relevant deformation mechanisms for diffusional and dislocation creep: elasticity with eigenstrains resulting from vacancy diffusion, dislocation climb and glide, and the lattice growth/loss at the boundaries enabled by diffusion. All the deformation mechanisms are described with respect to the...
متن کاملPredicting dislocation climb and creep from explicit atomistic details.
Here we report kinetic Monte Carlo simulations of dislocation climb in heavily deformed, body-centered cubic iron comprising a supersaturation of vacancies. This approach explicitly incorporates the effect of nonlinear vacancy-dislocation interaction on vacancy migration barriers as determined from atomistic calculations, and enables observations of diffusivity and climb over time scales and te...
متن کاملTHE EFFECT OF DY- DOPING ON THE STRUCTURAL AND MAGNETIC PROPERTIES OF MN-ZN FERRITE NANOPARTICLES
Mn0.8Zn0.2Fe2-xDyxO4 (where x= 0, 0.025, 0.05, 0.075, 0.1) ferrite nanoparticles were synthesized by auto- combustion sol-gel method for the first time in this study. The effect of Dy-doping on the structural and magnetic properties of the produced specimens was examined using the X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), vibrating sample magnetometery (VSM), and ...
