- Microstructural modification and grain refinement due to addition of scandium in Al-6Si-0.3Mg alloy has been studied in this article. It is seen from the microstructure that the dendrites of the cast Al-6Si-0.3Mg alloy have been refined significantly because of addition of scandium. Increasing amount of scandium leads to a greater dendrite refinement. The age hardening effect has been studied by subjecting the alloys containing varying amounts of scandium ranging from 0.2 to 0.6 wt.% to isochronal and isothermal aging at various temperatures for different times. It is observed that addition of scandium is the most effective in suppressing the softening effect during prolonged aging treatment.
