THE METHOD OF FORMING A COMPOSITE METAL BODY, COMPRISING THE STEPS OF: DISPOSING A PLURALITY OF ELONGATED ELEMENTS IN LATERALLY SPACED PARALLEL RELATIONSHIP TO DEFINE A CAGE; PLACING SAID CAGE IN A MOLD CAVITY; DRAWING A VACUUM IN SAID CAVITY; HEATING SAID CAGE TO A PRESELECTED PREHEAT TEMPERATURE; HEATING A QUANTITY OF MATRIX MATERIAL TO A TEMPERATURE; PRESELECTED AS A FUNCTION OF THE HEAT CAPACITY OF SAID ELEMENTS AND THE HEAT CAPACITY AND HEAT OF FUSION OF SAID MATRIX MATERIAL TO CAUSE SUBSTANTIALLY INSTANTANEOUS SOLIDIFICATION OF A THIN LAYER OF SAID MATRIX MATERIAL ON THE SURFACE OF THE ELEMENTS WHEN CONTACTED THEREWITH; AND INTRODUCING THE HEATED MATRIX MATERIAL INTO THE CAVITY TO CAST THE MATRIX MATERIAL ABOUT THE ELONGATED ELEMENTS OF SAID CAGE TO DEFINE A BILLET OF SAID ELEMENTS METALLURGICALLY BONDED TO SAID MATRIX MATERIAL.
