Abstract: Centrifugal Duplex Casting (CDC process) is applicable to produce an aluminum-cast pipe with an in-situ composite layer containing fine intermetallic crystals. In this process, two kinds of molten metal, i.e. molten aluminum (the first melt) and molten Al-Cr alloy with a higher liquidus temperature (the second melt), are cast in sequence at a given interval into the rotating mold of a centrifugal caster. In the present paper, the solidification structure, hardness and wear resistance of Al-Cr alloy pipes produced by the CDC process were investigated. In the composite layer, there was a slightly graded hardness distribution: the hardness decreased gradually as the distance from the outer periphery of the pipe increases. The profile of hardness resembled that of the volume fraction of intermetallic crystals. The hardness and wear resistance of the outside surface of the CDC pipes increased as the chromium concentration of the second melt or the rotation speed of the mold increased. The pipes with coarse intermetallic crystals, which were produced by the conventional centrifugal casting process, were fractured in the course of wear tests. On the other hand, the CDC pipes exhibited homogeneous-wear behavior because of the refinement of intermetallic crystals.
