Carbon Content and Crystal Alignment Found Critical for Magnetic Performance in Aged Electrical Steel Components
Scientists have discovered that carbon concentration significantly influences precipitate formation and magnetic characteristics in non-oriented FeSi steel. The study demonstrates how specific crystal orientations correlate with improved magnetic performance in electrical steel components after aging treatment.
Carbon Content Dictates Precipitate Formation
Recent research published in Scientific Reports reveals that carbon concentration plays a decisive role in precipitate formation during the aging process of non-oriented FeSi steel components. According to the study, samples with 0.41% carbon exhibited the highest volume fraction of cementite precipitates, while the 0.05% carbon sample showed negligible precipitate formation below 0.5 volume percent. The report states that increasing carbon content by two times more than doubles the number of precipitates formed during aging.
