Mechanistic Contribution of the Interplay between Microstructure and Plastic Deformation in Hot-rolled Fe-11Mn-2/6Al-0.2C Steel
We elucidate here the mechanistic contribution of the interplay between microstructural constituents and plastic deformation behavior in hot-rolled Fe-0.2C-11Mn-2Al and Fe-0.2C-11Mn-6Al steels.The steel containing lower aluminum content (2 weight %) quenched from 650℃ led to austenite and α-ferrite duplex microstructure,which was characterized by excellent combination of tensile elongation(TE) of 31%,ultimate tensile strength(UTS) of 1407 MPa.In contrast,the steel containing higher aluminum (6 weight%)quenched from 650℃exhibitedlower UTS of 659 MPa,but higher TE of 65%,which is resulted from the transformation induced plasticity (TRIP) effect and twinning induced plasticity (TWIP) effect.
