Thermodynamics of orientation discontinuity surface: small misorientation approach

摘要: The thermodynamics of a crystal lattice reorientation process proceeding on low angle grain boundary is presented. In material science, the influence misorientation energy well established. On other hand, in discontinuity surface vector usually ignored as yet. Therefore, present paper, attention focused this influence. To obtain driving forces conjugate to relative reorientation, continuum theory dislocations has been applied. Starting from balance law and assuming that free depends strongly jump orientation field, mathematical relations for conjugated thermodynamic force are derived. mentioned contributes total governing migration process. problem constitutive modelling motion considered. main result analysis incorporation into description
