Correlation Between Pre-annealing Temperature and {110}aOE (c) 001 > Annealing Texture in C- and Al-Free Fe-3 Pct Si-0.1 Pct Mn-0.002 Pct S Electrical Steel

摘要

In C- and Al-free electrical steel, the increase in primary grain size with increasing pre-annealing temperature causes the transition in annealing texture after final annealing from {110} + {100} to {110}. The strip pre-annealed at 1073 K (800 A degrees C) shows a low magnetic induction B-8(T) of 1.784 T after final annealing. The strip pre-annealed at 1223 K (950 A degrees C) shows a sharp {110}aOE (c) 001 > Goss texture, producing a high magnetic induction B-8(T) of 1.914 T comparable to that of the conventional electrical steels.
