Abstract TEM observations were made of the precipitated particles in two high induc-tion grain-oriented silicon stfeels with and without Sn. The inhibiting ability of precipitatedparticles in the Sn bearing material for primary grain growth was compared with that in theSn free one.The temperature dependence of the primary grain size for the two materials wasstudied. A comparison of the total intensity of inhibitors was made between the twomaterials.Based on the above results, it can be concluded that Sn plays a role of an impor-tant inhibitor through segregation on primary grain boundaries.
