摘要

A new micromechanical modelling is proposed to correlate some microstructural parameters and dissipation in ferritic steels under cyclic loading. We assumed the occurrence of two dissipative mechanisms associated with anelastic and inelastic deformations, respectively. We showed that the modelling provides good qualitative prediction of the heating curves when changing the volume fraction of precipitates in ferritic steels. We highlighted the key role of the dispersion of the grain size on the local and global dissipation.
