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.en© Springer Science+Business Media, LLC 2006The effect of dissolved titanium on the primary α-Al grain and globule size in the conventional and semi-solid casting of 356 Al–Si AlloyThe effect of dissolved titanium on the primary alpha-Al grain and globule size in the conventional and semi-solid casting of 356 Al-Si AlloyJournal article002010861610.1007/s10853-006-0866-129758Ghomashchi, R.
