Abstract: RESUMO Nos últimos anos, vários estudos foram realizados buscando reduzir o peso de veículos automotores, a fim de diminuir as emissões de poluentes. Neste cenário os aços de baixa densidade do sistema Fe-Mn-Al-C podem ser considerados uma alternativa promissora para suprir essas exigências da indústria automotiva. Geralmente, nos aços de baixa densidade, uma quantidade considerável de alumínio é adicionada a fim de reduzir a densidade geral do aço. No entanto, altos teores de alumínio promovem características… Show more

“…Previous research shows that the addition of Nb elements to N-free steels tends to produce small-sized NbC precipitation phases of tens to hundreds of nanometers [7,8]. Previous research shows that microalloying elements such as Nb and V have a significant effect on the recrystallization behavior of steel, which is mainly manifested by delaying the onset of dynamic recrystallization and refining the recrystallized grains [9,10]. DU et al [11] find that the thermoplasticity of the material increases with the degree of recrystallization during high-temperature deformation by studying the tensile properties of NiFeCoCrMn high-entropy alloy after machining.…”
