Claim 1
Independent Claim
185 words
THE METHOD OF PRODUCING ALLOYS HAVING HIGH STRENGTH AT ELEVATED TEMPERATURES WHICH COMPRISES THE STEPS OF HEATING A COMPACT OF A POWDER MIXTURE OF CARBON, A FIRST METAL SELECTED FROM THE GROUP CONSISTING OF MOLYBDENUM AND TUNGSTEN AND A SECOND METAL SELECTED FROM THE GROUP CONSISTING OF TITANIUM, ZIRCONIUM, HAFNIUM AND THORIUM TO A TEMPERATURE ABOVE THE MELTLING POINT OF SAID SECOND METAL AND BELOW THE MELTING POINT OF SAID FIRST METAL TO FORM A SINTERED BILLET CONTAINING THE SECOND METAL AND CARBON, RESPECTIVELY, IN THE AMOUNTS OF FROM ABOUR 0.40% TO ABOUT 0.60% AND FROM ABOUT 0.02% TO ABOUT 0.06%, THE BALANCE BEING SAID FIRST METAL, MECHANICALLY WORKING SAID BILLET AT A TEMPERATURE IN THE RANGE OF BETWEEN ABOUT 1350*C. AND ABOUT 1500*C. TO FORM A PLATE OF LESSER THICKNESS THAN SAID BILLET AND THEREBY CAUSING PRECIPITATION OF A CARBIDE OF SAID SECOND METAL FROM SAID FIRST METAL, REHEATING SAID PLATE AT A TEMPERATURE BETWEEN ABOUT 1650*C. AND ABOUT 2150*C. TO REDISSOLVE THE PRECIPITATED CARBIDE, AND THEREAFTER MECHANICALLY WORKING SAID PLATE AT A TEMPERATURE BELOW ABOUT 1400*C. TO AN ALLOY BODY OF DESIRED DIMENSIONS.
