%X The erosion behavior of a mixing impeller blade made of low carbon steel in molten aluminum alloy as function of time and rotational speed has been studied during process of stir-cast for Al alloys,and the relevant erosion mechanism is also discussed.The result shows that the erosion induced weight loss rate increases with the prolonging mixing time and the raising rotational speed.There is an incubation period of time,below which,erosion rate is very small.This incubation period decreases with the increase of rotational speed,and which decreases sharply when the rotational speeds exceed 1000 r/min.The erosion process in mixing aluminum alloy may involve processes such as blade surface cleaning,diffusion of aluminum atom onto and the intermetallic compound formation on and the compound removal from the blade surface.The rotational speed affects primarily the removal of the formed compound.
