Texture Effect on Magnetic Properties by Alloying Specific Elements in Non-grain Oriented Silicon Steels

抄録

The effect of texture on magnetic properties by adding specific elements of tin, antimony and boron was investigated. Texture factor was defined as the ratio of the sum of cube and Goss textures to γ fibre. Tin and antimony showed larger effect in enhancing grain size than boron for both hot rolled and cold rolled bands. Texture factor increased with an increase in grain size; that is, grain size effect on texture factor appeared larger for the addition of tin and antimony than for boron. Both tin and antimony showed large volume fractions of cube and Goss textures but low volume fraction of γ fibre compared to boron. The effect of texture factor on core loss was larger for tin and antimony added steels than for boron added steel. Magnetic flux density increased proportionally with the texture factor and the effect of texture factor on magnetic flux density was also greater in tin and antimony added steels than in boron steel.
