Abstract

Abstract

The microstructural evolution during partial remelting of dendritic AlSi Mg alloys was studied with the help of an electrical furnace. The results show that it is diffi-cult to change all the primary α dendrites into the spheroidal α phases, when the dendritic samples of AlSi₇Mg alloy are remelted under 589 or (597±1)℃ and held on this condition for 5 to 120 min. The results also show that the samples remelted can be deformed under the heavy force, if the holding time is longer under higher temperature.
