Analysis of the microstructure, texture and magnetic properties of strip casting 4.5wt.% Si non-oriented electrical steel

Abstract

Abstract The microstructure, texture and magnetic properties of 4.5 wt.% Si electrical steel fabricated by the processes of twin-roll casting, warm-rolling and final annealing were systematically investigated with the aim of introducing a remarkable and promising electrical steel with extensive potential applications. The results show that unusually sharp {411} texture is obtained in addition to common Cube, rotated Cube, Goss and {111} orientation after final annealing. Excellent magnetic inductions of 1.518 T (B 8 ) and 1.703 T (B 50 ), and iron losses of 24.92 W/kg (W 10/400 ) and 24.47 W/kg (W 5/1000 ) have been achieved.
