The authors investigate modifications in castability, temperature effects, porosity, and fracture properties in silicon-aluminium alloys after being alloyed with strontium and zirconium. The porosity observed in alloys containing strontium was found to have a microshrinkage character. Alloying with zirconium was found to reduce somewhat the tendency of the alloy toward the formation of microshrinkage porosity but did not compensate for the influence of strontium.
