Description High permeability commercial CRGO, cold rolled grain oriented steel was subjected to uni-axial tensile strain in three principal orientations: (110) < 001 >, (110) and (110). The samples exhibited remarkably different stress-strain behavior. The numerical values of the strain hardening exponent, n, largely determined the degradation in magnetic properties: namely increase in Hysteresis loss (H) and drop in Permeability (mu). Changes in magnetic properties were also correlated with microstructural observations: misorientation and dislocation density developments, relative recovery, residual strain and deviation from ideal < 001 >. The study established constitutive relationships between degradation in magnetic properties and various parameters of the deformed microstructures.
