Process for producing cube-on-edge oriented silicon iron

Claim 1

A PROCESS FOR PRODUCING SILICON-IRON BODIES HAVING A MAJORITY OF THE CONSTITUENT GRAINS ORIENTED IN THE (110)(001) TEXTURE, COMPRISING PROVIDING A SILICON-IRON BODY COMPOSED OF FROM 1.5 TO 4.0 PERCENT SILICON, BALANCE SUBSTANTIALLY ALL IRON AND CONTAINING MINOR ADDITIONS CAPABLE OF FORMING A SECOND PHASE DISPERSION, SAID ADDITIONS BEING UP TO ABOUT 0.15 PERCENT MAGANESE, UP TO ABOUT 2.0 PERCENT VANADIUM, UP TO ABOUT 0.10 PERCENT TITANIUM, UP TO ABOT 0.035 PERCENT CARBON, UP TO ABOUT 0.03 PERCENT SULFUR AND UP TO ABOUT 0.005 PERCENT OF NITROGEN, QUENCHING THE SILICON-IRON ALLOY FROM A TEMPERATURE NOT LESS THAN ABOUT 1325*C. WHERETHE MINOR ADDITIONS ARE IN SOLUTION AT A RATE RETAINING THEM IN SOLUTION, HEAT TREATING THE QUENCHED ALLOY AT A TEMPERATURE OF FROM ABOUT 900*C. TO ABOUT 110*C. PRECIPITATING A FINELY DIVIDED, EVENLY DISPERSED SECOND PHASE ASSISTING DEVELOPMENT OF THE (110)(001) GRAIN ORIENTATION, COLD ROLLING THE QUENCHED AND HEAT TREATED ALLOY TO A DESIRED FINAL THICKNESS, AND SUBJECTING THE COLD ROLLED ALLOY TO A FINAL RECRYSTALLIZING ANNEAL AT A TEMPERATURE OF FROM ABOUT 950*C. TO 1050* C. TO EFFECT SECONDARY RECRYSTALLIZATION THEREOF AND DEVELOP THE DESIRED (110)(001) CRYSTALLINE ORIENTATION.
