摘要 It is vital for emission reduction and energy saving to lighten the weight of automobile. Low-density Fe-Mn-Al-C steels with high strength and excellent ductility have become a promising type of material in the automotive industry. In this work, a new approach was proposed by using centrifugal casting to produce the low-density Fe-12Mn-9Al-1.2C steel with high performance under near-rapid solidification in a near-net shape. The produced steel strips, with a thickness of 2.5 mm and a density of 6.89 g/cm3, were examined for their microstructures and mechanical properties. The results showed that mechanical properties of as-cast steel strip reached 1,182 MPa in ultimate tensile strength, and 28.1% in total elongation. Aging treatment at 400 oC or 600 oC for 3 h enhanced tensile strength of the steel strips, while aging at 800 oC dramatically decreased its elongation. Moreover, Young’s modulus of the steel strip improved with the increment of aging temperature. The relationship between the mechanical properties and the microstructure was discussed. This work demonstrated that advanced low-density steels with promising mechanical properties can be directly produced from liquid by this simple process.
