Some various Al Fe Si alloys by centrifugal casting was conducted. The results showed that under the centrifugal field

primary phase in alloy migrated along the radical direction but the migration effects of the primary phase with various sizes were different. Meanwhile

the element concentration has different variation under the centrifugal field. The sloping changes of the primary phase distribution and the element concentration would results in the gradient variation of relevant properties and form functionally gradient materials to certain extent.
