In the present paper, a multiphysic model was developed to identify the underlying mechanism of surface layer hardening in burnishing of stainless steel 304. The mechanic of burnishing process was firstly modeled to obtain deformation parameters i.e. strain and strain rate by incremental plasticity. Then the strengthening mechanisms were identified association of constitutive equations regarding twinning-induced hardening and phase change. It was found that the twining-induced hardening has greatest contribution in strengthening the surface layer. Moreover, among the process parameters, the burnishing depth has greatest effect on hardness magnitude and corresponding depth.
