¦Á-Ti crystal will form in the melt before peritectic transformation, then ¦Á-Mg nucleation occurs attached on ¦Á-Ti and the fine dispersed ¦Á-Mg phases are formed. As temperature decreases, primary ¦Á-Mg is formed and the generated fine ¦Á-Mg phases by transformation act as crystallization

¦Á-Ti crystal will appear in the form of crastal in the melt before peritectic transformation,then ¦Á-Mg nucleation that attaches itself to the surface of  ¦Á-Ti will occur and the good dispersed ¦Á-Mg phases will be formed. As temperature decreases, As temperature decreases, the primary ¦Á-Mg is formed directly and the small particles of ¦Á-Mg generated  by transformation act as crystallization nuclei.
