摘 要：Non-oriented silicon steels containing different mass fractions of lanthanum were prepared using a high-frequency suspended furnace.Microstructures were observed by a metallographic microscope and micro-orientations were analyzed by a scanning electron microscope（SEM）.The results showed that at the annealing temperature of 870℃,recrystallization started at 90 s and completed at 120 s during annealing.Without lanthanum,no matter Cube or {111 }<110> grains,recrystallized grains nucleated mainly in deformed {111}<110> and {113}<031> grains.With lanthanum,however,they nucleated in the deformed {110} and {112}<132>grains.This indicated that addition of lanthanum changed the micro-orientation relationship between new grains and the matrix.
