The simulation of grain growth in magnetic field with the full distributions of grain orientation and grain boundary character

摘要

The Monte Carlo simulation of graingrowth with the two dimensional site lattice modelhas been carried out where: the orientations ofindividual grains are described with the threedimensional Euler angle; the characterization ofindividual grain boundaries and the estimation oftheir energy are made with the coincidence sitelattice model; and the effects of the surfaceenergy and the magnetic anisotropy are taken intothe account in a realistic manner. With a magneticor surface spectrum alone, grain growth slows twostages, the second stage being viewed as theabnormal grain growth. If both of them areconsidered, the two-stage growth is suppressed.These results are disscussed with simulatedtexture evolution and experimental results on amagnetic annealing of Fe-50%Co film.
