Abstract: The chemistry of molten alloy plays an important role on grain refining. Small addition of alloying elements reduces the grain size of the as-solidified structures to some degree depending on the alloy efficiency. The effect of dissolved Ti has been studied on the microstructure of Al–Si foundry alloys cast conventionally and by semi-solid casting routes. It is shown that Ti in solution could restrict the grains and globules size in both processes. A parallel plate compression test machine was employed to study the effect of dissolved Ti on the rheological behavior of the billets. It was confirmed billets with higher dissolved Ti-content have superior flow.
