Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
In this paper, anisotropy problems of three-dimensional phase-field model are studied, various degree of anisotropy were simulated by numerical calculating method. During the change of interface anisotropy coefficients, from smooth transition to the appearance of angle, balance crystals shape morphology has a critical value, three-dimensional critical value is 0.3. The growth of dendrites is stable and the interface is smooth when it is less than critical value, the interface is unstable, rolling edge appears and the growth is discontinuous when it is more than critical value. With the anisotropy coefficients becoming larger, the growth of dendrites becoming faster under the same condition.
