Abstract

In this paper, an attempt is made to characterize the in-house development of aluminium copper alloy (duralumin). Further the investigation moves to examine the effect of grain refiner process on microstructure of duralumin. The experimental process involves the casting process of duralumin with pure aluminium and master alloy (Al-40 wt%Cu.). For grain refinement of the duralumin, different fraction of Al-3Ti-0.15C grain refiner was added to the duralumin. The results highlight that the grain refiner with addition of 0.6% Al-3Ti-0.15C will be resulted in the reduction of grain size of duralumin.
