ABSTRACT
The development of a methodology to consistently produce Goss textured electrical steel sheet meant a big advancement
for the electrical steel industry. Grain oriented electrical steels are characterized for having a strong Goss texture, which means having the {110} planes parallel to sheet surface and the <001> directions parallel to the rolling direction. As <001> is the
easy direction of magnetization for Fe-á, magnetic flux density can be improved through the rolling direction. However, magnetic properties get to be inferior in all other directions. Grain oriented electrical steel are designed to be used on stationary applications
such as transformers, where the magnetic flux can be controlled to go parallel to the rolling direction, hence, parallel to the easy direction of magnetization. Throughout this work, the models proposed to explain Goss texture formation will be explained and
analyzed. Some concepts necessary to understand the topic will be covered such as texture, texture representation, recrystallization (nucleation and growth), and secondary recrystallization (the coincidence site lattice boundary model and the high energy boundary
model).
