Effects of magnetic field on grain growth of non-ferromagnetic metals: A Monte Carlo simulation

Abstract

The grain growth kinetics, texture and misorientation distribution function (MDF) evolutions of a non-ferromagnetic metal sheet with isotropic and anisotropic grain boundary under magnetic field are studied using a modified two-dimensions (2D) Potts model, in which the grain boundary migration is driven by the grain boundary energy and the difference in magnetic free energy between grains and their neighbors. Monte Carlo simulation results show that the texture and MDF evolutions of materials intensively depend on the magnetic field and grain boundary anisotropy, whereas the grain boundary growth kinetics is insensitive to the magnetic field.

Magnetically induced/enhanced coarsening in thin films

“…1, no influence of the scaling behavior is observed. Even though the texture depends on strength and direction of the external magnetic field [24][25][26][27][28][29]. In these simulations the increase of growth of well aligned grains is leveled by the decrease of growth of not well aligned grains.…”

Magnetically Enhanced Thin‐Film Coarsening by a Magnetic XPFC Model Allowing to Decouple Magnetic Anisotropy and Magnetostriction

“…[12][13][14][15] For instance, magnetic fields have been shown to increase the grain growth during the annealing of thin Ni films below the Curie temperature. [13] While various simulation attempts to predict the influence of magnetic fields on grain growth exist based on Mullins-type models, [16][17][18][19][20][21] their predictive power is questionable in view of the previous discussion. Within a series of papers, also the PFC model was extended to capture the fundamental physics of magnetocrystalline interactions.…”
