Abstract Scope The high-temperature deformation behavior of electrical steel is an important material parameter for the optimization of the hot rolling process, which has not been paid close attention in electrical steel research. In this study, hot compression tests were performed on two non-oriented electrical steels containing 1.2 and 3.2 wt % Si. The samples were deformed up to a true strain of 0.7 at strain rates varying between 0.01 and 1 s-1, and temperatures ranging from 850 to 1050 C. The stress-strain data was fitted using various constitutive models, and evaluated using the correlation coefficient (R) and the average absolute relative error (AARE). It was shown that the modified Zerilli-Armstrong model provided excellent prediction of the flow stress in a wide range of strain, strain rate and temperature. Microstructure examination was performed to unravel the differences between materials with and without phase transformation during high-temperature deformation of the two different grades.
