The formation and growth behavior of the Zr primary compounds in Al-Zn-Mg alloys corresponding to the 7N01 alloy containing Cr, Mn, Zr and Ti has been investigated. Time, t (min), necessary for crystallization of the Zr primary phase of (Zr, Ti) Al3 from liquid is found as:t=0.167•exp(0.143/[%Zr]+0.909[%Ti]-0.138)(at 654°C)These compounds grow up to about 30μm within 30 minutes after beginning of crystallization. The fomation behavior of the compounds in continuous casting was also studied and discussed with the above equations. It is possible to predict and prevent the precipitation of the compounds in continuous casting by applying the above equation.
