Abstract The effect of decarburizing process on the magnetic properties of the grainoriented 3%Si-Fe has been studied. An empirical expression for the rate of decar-burization under given conditions was proposed. While the time of decarburizationwas given, the carbon content in 3%Si-Fe might be predicted, and vice versa.Another empirical expression for the rate of grain growth was also derived fromobservation of normal grain growth during decarburization. Based upon the aforementioned expressions, the functional dependence of thecarbon content before secondary recrystallization and time required for decarburi-zation on final magnetic properties of the grain oriented 3%Si-Fe has been dis-cussed. A two-demensional plot was then drawn on which the decarburizing pro-cess would be easily determined to acquire materials of superior quality.
