Abstract
This article deals with the effect of 0.25-1.5 wt pct mischmetal (MM) addition on the mechanical properties, microstructure, electrical cond uctivity, and fracture behavior of cast Al-7Si-0.3Mg (LM 25/356) alloy . Modification of eutectic silicon by MM is compared with strontium mo dification in terms of microstructure, mechanical properties, and fadi ng behavior. Loss of magnesium encountered on holding the molten alloy and its resultant effect on mechanical properties of alloys modified with MM and Sr are compared with those in the unmodified alloy.
