Fibers of molybdenum, TZM molybdenum, and tungsten were incorporated within a matrix of four different superalloys by extruding mixtures of spherical powders. Process feasibility, being a function of the flow characteristics of the coexisting materials, occurred only with certain materials, and at certain extrusion temperature. In these cases, fiber aspect ratios were sufficient, theoretically, to obtain fiber strengthening.
