Figure 9. Reducing density of steels for automotive applications

Figure 9. Reducing density of steels for automotive applications: (a) density as a function of aluminum content for binary Fe-Al18 and for quaternary 0.2C−8.5Mn (wt.%) alloys, wherein the continuous line corresponds to the density calculation for the quaternary system using Thermo-Calc [39]; (b) elongation (TE) as a function of ultimate tensile strength (UTS) in Fe–Mn–Al–C alloys (solution-treated and water-quenched strips) [40].
