摘要: Nanostructures of two non-oriented electrical steels were investigated in order to elucidate the influence nanostructure and its components on magnetic properties. The main difference between samples was related mean grain size level core loss. Surprisingly, sample with coarser ferrite grains exhibited higher For this reason (HR)TEM imaging carried out. Precipitation reactions monitored using differential scanning calorimetry (DSC). Light microscopy, FE-SEM/EDX EBSD analyses also performed analyse microstructures crystallographic textures. results compared It shown that besides microstructural components, nanoprecipitates have a crucial impact
