The results show that Tn1 (first characteristic temperature of primary crystal nucleation), Tn2 (second characteristic temperature of primary crystal nucleation) and Tch (temperature of dendritic coherency) decrease with the increasing of zinc content, and the temperature difference of (Tn1-Tn2) grows slowly while the temperature difference of (Tn2-Tch) almost remains constant; The results also show that the fs-cc (solid fraction of dendritic coherency) of AZ6x alloys is about 0.27~0.35 while AM60 and AZ66 alloys having higher fs-ch and alloys with 2~5wt% zinc content having lower fs-ch and AZ62 alloy having the lowest fs-ch; The results also show that Tpk (temperature of dendritic packing) decrease with the increasing of zinc content, and the solid fraction at Tpk decreases with the increasing of zinc content, and the mushy zone strength at Tpk increases first and then decreases with the increasing of zinc content while mushy zone strength of alloys with 2~5wt% zinc content having relatively slow increasing speed. the results obtained by cooling curve thermal analysis method and continuous torque measurement technique are accordant to each other.
