Abstract (en)
[origin: WO2015158328A1] The invention relates to a method for calculating the combination of properties of phase components and of mechanical properties being established of a predefined alloy composition for a deformable lightweight steel having the elements in percent by weight C 0.02 to ≤ 1.0, Al 2.5 to ≤ 8.0, Si 0.0 to ≤ 1.5, Mn ≥ 5.0 to ≤ 35.0, Cr > 1.0 to ≤ 14.0, total content of N, S, P ≤ 0.1, the remainder iron and other steel-accompanying elements with some contents of Cu, Mo, Ni, and Zn of up to 1.0 wt% in total by using specific formulas on the basis of the manganese content, wherein, in the formulas, the alloy contents are used as absolute numbers without dimensions, and the calculated, dimensionless values are assigned the units MPa for Rm and Rp and % for A80. The invention further relates to a method for the further processing of a lightweight steel produced having a predefined alloy composition to form a hot-rolled strip.
