Abstract：In order to study the effect of annealing temperature on microstructure,texture and magnetic properties of ultra-thin grain-oriented silicon steel for medium/high frequency application,an ultra-thin grain-oriented silicon steel with a thickness of 0.08 mm was prepared by the primary recrystallization method using the commercial 0.27 mm glassless grain-oriented silicon steel plate as raw materials. Effects of annealing in the range of 800 ℃ to 1 000 ℃ on annealed structure,texture and magnetic properties of ultra-thin oriented silicon steel were systematically investigated. It was found that,due to forming high-angle misorientation grain boundary with surrounding deformation matrix,the η oriented ({0kl}<100>) grains in transition bands preferentially nucleated by bulging of initial grain boundaries. With the increase of annealing temperature,average recrystallized grain size increased,the size advantage of non-η oriented grains such as {114}<481> grains became more obvious,the volume ratio of η oriented grains decreased and grain uniformity turned worse. Ultra-thin oriented silicon steel had better comprehensive magnetic properties when annealing temperature was slightly lower and the magnetic induction intensity and the core loss was 1.82 T and 11.66 W/kg respectively,best comprehensive medium frequency magnetic properties in the present experiment condition when annealing temperature was 800 ℃.
