The effects of adding different contents of Nb on microstructure an d magnetic properties of Fe 6.5 wt.%Si alloy were investigated. The results show that the addition of a suitable amount of Nb to Fe 6.5 wt.wt.%Si alloys has improved the ductility of the alloy by precipitating Nb Fe Si intermetallics The precipitated Nb Fe Si particles have refined the grains and lowering the Si content in the matrix, the latter effect has resulted in the reduction of the ordered phases or the degree of long range order in the alloy. However, when the Nb content is 2.0wt.%, the numbers of precipitates are too high and starting to p in the movement of dislocations, which has an adverse effect on the processability of the alloy. Thoug h the Fe 6.5Si 1.5Nb (wt.%) alloy showed better magnetic properties than the Fe 6.5Si 2.0Nb (wt.%) alloy, the addition of Nb would deteriorate the magnetic properties of Fe 6.5wt.%Si alloy . Thus, the addition of Nb should be less than 1.5 wt.% to balance t he processability and magnetic properties of Fe 6.5wt.%Si alloy..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
