Notes:
Equal channel angular extrusion (ECAE) was employed in an attempt to developnanostructural metal matrix composites with homogenized distribution of reinforcing particles. Zn-Al metal matrix composites reinforced with 5 μm SiC particulates were produced by castingmethod. A non-uniform distribution of the reinforcing particles was evident in the metal matrix.With repetitive shear deformation imposed via the ECAE process, substantial structuralimprovement was achieved and the reinforcing particulates were de-clustered into a finely disperseddistribution throughout the metal matrix. The homogeneity of the particle distribution was studiedby the Quadrat method and the skew factors were determined. It was found that the skew factorswere substantially reduced after 8 extrusion passes, showing the homogeneity of the particledistribution was greatly improved in the composites
