EFFECT OF THICKNESS ON SECONDARY RECRYSTALLIZATION OF FE-3-PERCENT-SI

A study was made on the effect of the final thickness (0.60-0.18 mm) o n the secondary recrystallization of Fe-3%Si using MnS and AIN as inhi bitors. When heated in hydrogen during final annealing, the 0.60 mm th ick specimen underwent a complete secondary recrystallization, but the 0.36 mm and thinner specimens did an incomplete secondary recrystalli zation. When heated in a mixture gas of hydrogen and nitrogen during f inal annealing, all specimens underwent a complete secondary recrystal lization, but the thinner the specimen, the lower the magnetic flux de nsities were. The reduction of final thickness makes the specimen too sensitive to the atmosphere during final annealing to get a precisely Goss-oriented secondary-recrystallized texture.
