In this work, the hot deformation behavior of Fe-8Mn-7Al-5Ni- xV( x = 0, 0.4, 0.8)-0.3C low-density steel has been investigated at 950, 1000, and 1050 °C, along with strain rates of 0.01, 0.05 and 0.1 s−1. The constitutive equation and processing maps are established, and the microstructure of unstable regions and the influence of V element on DRX are analyzed. The optimum hot working conditions of 0 V steel, 0.4 V steel, and 0.8 V experimental steel fall within a strain rate of 0.01∼0.02 s−1. The optimum deformation temperatures are about 950 °C, 1050 °C, and 950∼970 °C or 1020∼1050 °C, respectively. Adding V element leads to the formation of the VC precipitation phase in ferrite, consuming many carbon atoms and weakening austenite stability in the steel.
