Correlation Between Pre-annealing Temperature and {110}〈001〉 Annealing Texture in C- and Al-Free Fe-3 Pct Si-0.1 Pct Mn-0.002 Pct S Electrical Steel

Abstract

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?��C) shows a low magnetic induction B8(T) of 1.784?T after final annealing. The strip pre-annealed at 1223?K (950?��C) shows a sharp {110}��001�� Goss texture, producing a high magnetic induction B8(T) of 1.914?T comparable to that of the conventional electrical steels. ? 2017, The Minerals, Metals & Materials Society and ASM International.
