Abstract

These studies were made to investigate the effects of Si on the recrystallization of Al-Mn alloy.
(1) Si had remarkable effects on the recrystallization temperature of Al-Mn alloy. When its sheet ingot was not preheated, Si raised the recrystallization temperature. Whereas, when it was preheated. Si lowered the temperature.
(2) Heating rate also had effects on the recrystallization temperature of non-preheated Al-Mn alloy containing Si. The elevation of temperature was remarkable in slow heating, and it was maximum at the heating at 160°C.
(3) Si decreased the effects of heating rate on the grain size of recrystallized Al-Mn alloy when the sheet ingot was not preheated. It gave a fine grain size even at slow heating rate. Whereas, Si increased the effects of heating rate on the grain size of the preheated alloy and a large grain size was produced by slow heating.
These phenomena resulted in that Si prevented the effects of preheating on the refining of the recrystallized grains of Al-Mn alloy; and the grains obtained at the normal heating rate, which was slower than that in a salt bath, were coarser than those obtained after no preheating.
