摘要: Abstract In the present work influence of intermediate annealing and strain path during a two-stage cold rolling on microstructure texture 1 wt% Si non-oriented electrical steel was investigated. Different processing conditions were tasted to develop favorable better understand relation between important magnetic properties. The parameter (TP) defined as “theta fiber/gamma fiber” ratio. results showed that samples with highest TP have lowest anisotropy. Also average magnetocrystalline energy calculated it demonstrated can be correlated Regardless condition process, uni-directional produced very similar (~2). However, cross rolled different parameters upon annealing. after at 650 °C (~3). proposed thermo-mechanical allow diminishing gamma fiber which is deleterious for properties steels.
