摘要：
The fabrication of the intermetallic compound-dispersed functionally graded materials (FGMs) by a centrifugal method can be classified into two categories based on the relation between the processing temperature and the liquidus temperature of master alloy. One is a centrifugal solid-particle method where the processing temperature is lower than the liquidus temperature of the master alloy and the dispersed solid phase in the master alloy remains in a liquid matrix. The other is a centrifugal in-situ method where the processing temperature is higher than the liquidus temperature of the master alloy. The FGMs introduced in this review are Al-Al3Ti FGM fabricated by the centrifugal solid-particle method, Al-Al3Ni FGM, Al-Al2Cu FGM fabricated by the centrifugal in-situ method and Al-(Al3Ti+ Al3Ni) FGM fabricated by both methods. In this review, the outline of the method is introduced briefly, and then described some recent studies about the microstructures of the FGMs fabricated by the centrifugal solid-particle and/ or in-situ methods.
