Effect of Heating Rate and Annealing Temperature on Secondary Recrystallization of Goss Grains in a Grain Orientated Silicon Steel

In this investigation, a grain oriented silicon steel was annealed from a starting state of its primary recrystallized condition by varying time, temperature and heating rate to elucidate the phenomena that occur during the secondary recrystallization growth of Goss grains. Goss secondary recrystallization occurs in a temperature range from 900 to 1000°C. Using a slow rate of heating (5°C/minute) to the annealing temperature yields more...
