Abstract
A pellet for fabricating a metal matrix composite is made of a mixture of a matrix member of a metal powder and at least one reinforcement selected from whiskers, short fibers and suitable particles, the reinforcement being uniformly distributed in a matrix of the metal powder and said mixture being kept in a shape with a binder, wherein said pellet has a surface layer of dried and rigid portion of said mixture which is rigid enough to keep its shape under an external pressure applied thereto. The pellet is formed from a flat cake of the mixture separated from a slurry consisting of a solution medium and the mixture dispersed therein uniformly. Alternatively, the pellet is formed from the mixture in a dried condition with a granulation binder diluted with a solution medium.
