Influence of Carbon on the Stacking Fault Energy and Deformation Mechanics of Fe-Mn-C System Alloys

Article Preview

Abstract:

Fe-Mn-C alloys with different carbon content were investigated. It was found that carbon element effected the SFE of the Fe-Mn-C alloys seriously, SFE increases with increase of carbon concentration. Fe-Mn-C alloys' deformation mechanisms, with SFE increase from 9.04 mJ.m-2 to 39.99 mJ.m-2, turn transformation-induced plasticity (TRIP) effect into twinning-induced plasticity (TWIP) effect with carbon concentration increase from 0.16% to 0.98%.
