چکیده مقاله:
Functionally Graded Materials (FGM) containing microstructural features intentionally varied from surface towards interior area of a component, exhibits attractive surface mechanical properties such as wear behaviour. In the current work the effect of rotational speed on the distribution of primary Si in an Al-17wt%Si alloy cast via centrifugal casting method was studied. Results show that, the optimized condition from the microstructural point of view, i.e. primary Si distribution and volume fraction within the surface area, was obtained at the rotational speed of 1400 rpm. The mechanical properties such as hardness and wear behaviour are also reported.
