Metal production

Claim 1

A METHOD FOR PRODUCING A HOMOGENEOUS TITANIUM BASE ALLOY COMPOSITION, COMPRISING PRESSING INTO A COHERENT, PARTIALLY DENSE COMPACT AN INTIMATE POWDER MIXTURE OF AT LEAST 50% BY WEIGHT OF DUCTILE TITANIUM AND NOT MORE THAN AN EQUAL WEIGHT OF AT LEAST ONE ALLOYING METAL HAVING A BOILING POINT ABOVE 1700*C., WHICH IS SOLUBLE IN PURE TITANIUM AT TEMPERATURES ABOVE ITS TRANSITION TEMPERATURE, PARTIALLY HOMOGENIZING SAID COMPACT THROUGH HEATING AT TEMPRATURES RANGING FROM ABOUT 900-1500*C. FOR FROM ABOUT 1-30 MINUTES UNTIL PARTIAL BONDING OF THE ALLOYING METAL WITH THE TITANIIUM TAKES PLACE AND TO FORM A PRODUCT HAVING AT LEAST 70% DENSITY, AN ELONGATION OF NOT LSS THAN 50% OF THAT OF A SPECIMEN OF IT UNALLOYED TITANIUM MATRIX SIMILARLY TREATED, AND A TESILE STRENGTH OF NOT MORE THAN 150% OF SAID SIMILARLY TREATED MATRIX, SAID PRODUCT BEING CAPABLE OF REDUCTION IN THICKNESS UNDER COMPRESSION AT ROOM TEMPERATURE TO AT LEAST 35% WITHOUT EDGE CRACKING, SUBJECTING THE PARTIALLY HOMOGENIZED PRODUCT TO WORKING AT A TEMPERATURE BELOW 600* C. AND UNTIL NOT LESS THAN 40% REDUCTION IN CROSS-SELECTIONAL AREA IS OBTAINED, AND THEN HEAT TREATING THE RESULTING PRODUCT AT TEMPERATURES RANGING FROM ABOUT 850*C.-1600*C. TO CONVERT IT TO A METALLURGICALLY HOMOGENEOUS ALLOY.
