Abstract
By using the elastic dipole model of strained crystals, we regard every atom in a binary crystal as an elastic dipole, which has various effective moment. On various kinds of atoms, different force will be acted by the stress field due to other stronger internal stress sources such as dislocation, inclusion, etc. Thus different displacement will take place and some domains of various shape depending on the relative magnitude of permanent moment and induced moment will form. In the present paper, the domain patterns produced by internal stress field of edge dislocation, screw dislocation, inclusion and crowdion are obtained by calculation, they look like rosettes Under proper condition the patterns of these domains might be observed. The result also shows the effect of pressure on phase transition.
