摘要：
A 3.2 wt.%5i-0.7 wt.%Al non-oriented silicon steel as-cast sheet with developed columnar grains and lambda-fiber (< 001 > parallel to ND) texture was produced by twin-roll strip casting process, and subsequently treated with cold rolling and annealing. Texture evolution at each condition was investigated using macro-/microtexture analysis. It was shown that the cold rolled sheet was characterized by pronounced {001} < 110 > similar to(115) < 110 > fiber and quite weak gamma-fiber (< 111 > parallel to ND) texture. After annealing, the recrystallization texture was dominated by desirable lambda-fiber with a peak at {001} < 510 > together with extremely weak gamma-fiber, and consequently the magnetic induction was significantly improved. It was indicated that the formation of {001} < 510 > recrystallization texture could be attributed to the preferred nucleation and grain growth by the strain-induced grain boundary migration (SIBM) mechanism.
