Characterization on Primary Phase Morphology of Semisolid A356 Alloy during Isothermal Holding with Fractal

摘要：

　　Semisolid A356 alloy was prepared by low superheat pouring,and evolution of primary phase morphology in semisolid A356 alloy during isothermal holding was characterized by fractal theory.The results indicated that the primary phase morphology in the alloy had fractal character,and the evolution of the primary phase morphology in the alloy could be characterized by fractal dimension.The primary phase morphology at the different isothermal holding temperature and holding time had the different fractal dimension,which meant the effect of processing conditions on the morphology in the alloy.Solidification of the alloy was a course of change in fractal dimension.
