Claim 1
Independent Claim
79 words
A METHOD OF FIBERING A REFRACTORY MATERIAL IN SITU COMPRISING THE STEPS OF MIXING 5 TO 16 VOLUME PRECENT OF EQUIAXED PARTICLES OF THE REFRACTORY MATERIAL TO BE FIBERED WITH A POWDERED METALLIC MATRIX MATERIAL HAVING A MELTING TEMPERATURE HIGHER THAN THE TEMPERATURE AT WHICH SAID EQUIAXED PARTICLES ARE DEFORMABLE, COMPACTING THE MIXTURE IOSTATICALLY TO FORM A BILLET, HEATING SAAID BILLET TO AN ELEVATED TEMPERATURE ABOVE 3700*F., AND ELONGATING SAID PARTICLES BY EXTRUDING SAID BILLET AT SAID ELEVATED TEMPERATURE.
