Abstract

ABSTRACT
In this work a number of cast samples of A356 and A390 were prepared by rheocasting
in a specially designed and built furnace unit allowing for the addition of the
nano-particles into the molten Al-Si alloy with mechanical stirring. The microstructure
features and the mechanical properties of the cast samples were investigated, as
well as resistance to wear and corrosion in laboratory tests.
The results obtained in this work showed improved wear and corrosion resistance of
the nano-dispersed hypereutectic A390 alloys, as well as enhancement in the
mechanical strength of the nano-dispersed hypoeutectic A356 alloys, accompanied
by significant increase in the elongation percentage, supported by evidence of
refined dendrite arms length, and inter-lamellar spacing. The work also shows
significant enhancement in the wear and corrosion performance of the nanodispersed
alloys.
