6.5wt% Si Electrical Sheet Produced by Laminar Composite Technique with Thermo-mechanical Process

Abstract

Fabrication of 6.5wt%Si electrical thin sheet by laminar composite technique and thermo-mechanical process was presented in this article. Morphology and elements content variation over thickness of each layer of the composite plate contains outer, transition and inner layers are investigated respectively during different stages of deformation and heat treatment procedures. Iron loss value of the homogeneous sheet was measured after diffusion annealing and a series of gradient high silicon electrical steels could be obtained by controlling the diffusion route.
