Abstract
Three different Al-alloys were solidified in metallic molds under the application of magnetic field and direct current with the aim of improving its structure and mechanical properties. The results obtained from these experiments indicate that increasing the stirring power causes a remarkable grain refinement and improvement in the mechanical properties. The stirring force which was created from the the interaction between a magnetic filed of 1860 causes and a direct
current of 230 amperes, Improves the ultimate tensile strength of the commercial pure Al( 99.5% ) by about 20% and its hardness by 42%. Corresponding values were (615 and 30%) and (62% and 25%) for the Al-4.3% Cu and the Al-11.7% Si alloys respectively. This improvement is most probably due to crystal multiplication and dendritic arms shearing.
