The Precipitation of Copper in the Non-Oriental Electrical Steel

Article Preview

The precipitation of copper in the non-oriental electrical steel was studied in this article. These precipitation particles, which influenced both the texture development and the magnetic properties of the steel sheets, appeared in the hot-rolling strips and grew up in the later normalization process. Their composition, morphology and crystallography had been investigated using TEM. Differed from the MnS and AlN that studied in the previous papers, these precipitate particles were found to be CuAl2. It suggested that these particles might stimulate the recrystallization nucleation of the {110} oriented grains and restrain the development of {111} oriented grains in the sheet of non-oriented electrical steel. This might be another explanation to the improvement on magnetic properties of the non-oriental electrical steel containing copper addition.
