Abstract

In this research, efficiency of grain refinement of permanent mold cast B319 aluminum alloy using titanium carbide (TiC) grain refiner was investigated. The grain refiner was added at 0.031, 0.05 and 0.1 wt%. In-situ solidification analysis was carried out, along with microsctructure and mechanical testing characterization. The results of cooling curve analysis suggest that addition of TiC delayed the time to reach the solidus temperature, increased the liquidus temperature, and decreased the amount of undercooling. Scanning Electron Microscopy (SEM) and chemical analysis revealed that Ti was present in solution uniformly throughout the matrix.
