Definitions
- the invention relates to a deformable lightweight structural steel with TRIP (Transformation Induced Plasticity) and TWIP (Twinning Induced Plasticity) properties according to the preamble of claim 1.
- Formable lightweight structural steels of this type are known (DE 10 2004 061 284 A1, DE 197 27 759 A1, DE 101 285 44 A1). In the case of these and comparable steels, in the presence of residual stresses in the material, depending on the microstructure and the strength, a hydrogen-induced delayed embrittlement and as a result cracking may occur.
- the object of the invention is to provide a lightweight steel of the generic type, which does not have the effect of a delayed hydrogen embrittlement while maintaining very good mechanical properties (ductility, strength).
- the problem mentioned in the problem is solved by a new alloy concept.
- This is characterized in that a lower C content is assigned to a lower Mn content and a lower C content to a higher Mn content, the C-Mn value pairs in a C-Mn coordinate system being approximately at a straight connecting line which has a distance to the connecting line of in equilibrium between ⁇ - (austenite-kfz) and ⁇ '-phases (martensite-krz) are located C-Mn value pairs.
- This new alloy concept makes use of the knowledge that the ⁇ -austenite (kfz) and the ⁇ -martensite (hdp) phase have a high hydrogen solubility while the ⁇ '-martensite (krz) phase has a much lower hydrogen solubility having.
- TRIP effect occurs, depending on the alloy composition, formation of the ⁇ '-martensite phase, e.g. via the metastable ⁇ -martensite phase.
- the densely packed ⁇ -Martensit phase can be present on the principle of least constraint even after the forming and fold down on discharge in the ⁇ '-martensite phase.
- the addition of Al and Si is approximately equal.
- the carbon content is a crucial element in the proposed alloy concept because it stabilizes the austenite phase and displaces the hydrogen from the free lattice sites.
- alloys have
- the first alloy example After annealing at 85O 0 C, the first alloy example has a yield strength R p0 , 2 of 480 MPa and a strength of 850 MPa with an elongation A of 58%. These values for the second example also alloy after annealing at 85O 0 C, R p o i2 450 MPa; R m 790 MPa and A 53%.
- a second parameter is the product of strength x elongation, which is a measure of the material's performance. This value is 49,300 for alloy example 1 and 41,870 (% x MPa) for example 2.
- the C content is plotted against the Mn content in a coordinate system.
- the solid straight connecting line shows the C-Mn value pairs which are in balance with respect to the ⁇ -austenite and the ⁇ '-martensite phase taking into account AI and / or Si addition.
- the dashed connecting line which is at a distance from the equilibrium line, identifies value pairs of the optimal alloy concept, with regard to material properties while avoiding delayed fracture.
- the shading applied over the dashed connecting line is intended to indicate the qualitative scattering band within which optimum results are still to be expected.
