Claim 1
Independent Claim
185 words
A PROCESS FOR BONDING TOGBETHER DUCTILE METALLIC LAYERS TO FORM A MULTILAYERED BODY OF METALLIC LAYERS WHEREIN EACH METALLIC LAYER IS BONDED TO ITS FACING LAYER BY A SUBSTANTIALLY CONTINUOUS METALLURGICAL BOND CHARACTERIZED BY THE PRESENCE OF A HOMOGENEOUS MIXTURE OF THE METALS OF THE RESPECTIVE FACING LAYERS WHICH COMPRISES SUPPORTING AT LEAST ONE METAL LAYER SEPARTED FROM AN ADJACENT METAL LAYER BY A SPACE OF AT LEAS 0.001 INCH AND IN SUBSTANTIALLY PARALLEL RELATIONSHIP THERETO, PLACING A LAYER OF A DETONATING EXPLOSIVE ON THE OUTSIDE SURFACE OF ONE OF THE METAL LAYES, SAID EXPLOSIVE HAVING A DETONATION VELOCITY OF GREATER THAN 1200 METERS PER SECOND BUT LESS THAN 120% OF THE SONIC VELOCITY OF THE METAL HAVING THE HIGHEST SONIC VELOCITY IN THE YSGEM, AND INITATING SAID EXPOLSIVE SO THAT DETONATION IS PROGAGATED PARALLEL TO SAID METALLIC LAYERS, THE LOADING OF SAID EXPLOSIVE BEING AT LEAST SUFFICIENT TO PRODUCE A PRESSURE UPON COLLISION OF SAID METALLIC LAYERS, SAID PRESSURE BEING GREATER THAN THE ELASTIC LIMIT OF THE METAL HAVING THE LOWEST ELASTIC LIMIT IN THE SYSTEM AND SUFFICIENT TO CAUSE BONDING BETWEE SAID LAYERS.
