secondphase dispersoids and SiC/Al interface of composite plate during wedge pressing were observed.The results reveal that the composite blank can be densified by wedge pressing

and boundaries at deposited particles are eliminated by wedge pressing with 50% in reduction

and relative density of the pressed composites reaches up to 97.6% with homogeneous SiC particle distribution.However

the dispersed pores are difficult to be eliminated by wedge pressing because of its low shearing forces.Dispersoids still keep with 60

00 nm in diameter from growing obviously and transforming into equilibrium phase such as Al13 Fe4 during the wedge pressing at 480℃.SiC/Al interface of the composite plate as-wedge pressed exhibits clean

which is contributed to the wettability between SiC

and Al matrix.
