%X The SiC_w/6061Al composite prepared by squeeze casting has a combi- nation of superior room temperature specific strength and modulus together with ex- cellent thermal properties. The extrusion can make an improvement on the strength and ductility of the composite from 582 MPa as squeeze casted up to 639 MPa, and on the transformation from isotropic to the anisotropic structure. This seems to be explained by the orientation of whiskers and the densification of dislocations in matrix. TEM observation indicates that the stacking fault is the usual planar defect on the SiC_w surface.
