Definitions

the invention relates to a method for producing a steel alloy for the production of strips, sheets and tubes for a low-alloy, high-strength carbide-free bainitic steel according to claim 1.
the invention relates to tubes, strips, and sheets made of this alloy, from which e.g. Components for the automotive industry, such as body panels, components of support structures or airbag tubes and cylinder tubes are produced.
Components for the automotive industry such as body panels, components of support structures or airbag tubes and cylinder tubes are produced.
wear plates made of this alloy can be used for excavator buckets.
steels are used for applications where sudden impact energies must be absorbed, e.g. as bulletproof armor.
Tubes made from this alloy can be designed as welded, hot or cold strip or seamless tubes, which may occasionally have deviating from the circular cross-sections.
Construction tubes or sheets of this steel alloy can also be used for highly stressed welded steel structures, for example in crane, bridge, ship, hoist and truck construction.
Characteristic of these steels is e.g. a strength of 1000 to about 2000 MPa, depending on the strength of an elongation at break of at least 5% and a very finely (nano-) structured bainitic structure with shares of retained austenite.
Carbide-free bainitic steels for rails are eg from the DE 696 31 953 T2 known.
the steel alloy disclosed therein in addition to additions of manganese, chromium and other elements such as molybdenum, nickel, vanadium, tungsten, titanium and boron, a silicon content between 1 and 3%.
This steel is designed for the requirements of highly wear-stressed rails, but for tapes, sheets and tubes for the stated application uneconomical or not applicable, since in addition to the requirements for wear resistance, both the strength and toughness requirements are met.
the cross-sectional dimensions of the rails differ significantly from those of the strips, sheets and tubes due to their compact cross-section, which means that the alloy concept can be adapted with regard to the required material properties after the air cooling of the steel required.
a disadvantage of the known steel is also the expensive addition of titanium and other alloying elements such as nickel, molybdenum and tungsten.
Another problem with the known steel is that no information is made on the nitrogen content, which exerts a negative influence on the material properties, in particular with aluminum additions by the formation of aluminum nitrides.
the object of the invention is to provide a method for producing a steel alloy for a low-alloy, high-strength, at the same time tough and wear-resistant carbide bainitic steel for the production of strips, sheets and tubes, on the one hand cheaper than the known steel alloys and on the other hand uniform, the requirements appropriate material properties, such as strength, elongation at break, toughness etc. guaranteed. moreover These material properties should be achieved by air hardening even when cooling to still air.
rare earths and reactive elements such as Ce, Hf, La, Re, Sc and / or Y can be alloyed with a total of up to 1 wt .-%.
steels according to the invention After lapping in air, steels according to the invention have a strength (R m ) of more than 1250 MPa, an elongation at break of more than 12% and a toughness (KBZ) of at least 15 J at -20 ° C. in the state of lumps or slabs (see Table 1 ) .
the structure consists of carbide-free bainite and retained austenite with a content of at least 75% bainitic ferrite, at least 10% retained austenite and up to a maximum of 5% martensite (or martensite phase and / or decomposed austenite).
the steel alloy according to the invention is based on the development of the DE 696 31 953 T2 and WO 2009/075494 A1 known carbide-free bainitic steel on.
chromium in the range of 0.10 to 2.00 wt .-%, moreover, the kinetics of ferrite formation can be decisively controlled, so that the formation of coarse polygonal ferrite grains, which can adversely affect the material properties, is effectively avoided.
Crucial here is the interaction of aluminum and chrome. While aluminum accelerates the ferritic and bainitic transformation, the addition of chromium retards ferritic transformation (see p FIG. 2 ). Through a specific combination of these two elements, both the kinetics of ferrite and bainite formation can be controlled.
the nitrogen content be as specified
the upper limit of 0.025 wt.%, Better still 0.015 wt.% Or optimally 0.010 wt ⁇ 10 -3 (wt .-%) must be satisfied.
a minimum content of nitrogen 0.001 wt.%, Optimally 0.0020, is required to allow niobium carbonitride formation necessary to increase the toughness by grain refining.
the investigated alloy compositions and the determined mechanical characteristics are given in Table 1 . All samples were heated to about 950 ° C and then cooled in still air or accelerated. The required cooling rate is made dependent on the sheet thickness and the composition. As the results of the mechanical sampling show, the required properties could not be achieved with the test melt 14 because of the too low Cr content.
the experimental melt 16 according to the invention fulfilled the requirements because of the larger sheet thicknesses of 12 mm only by accelerated cooling. Typical temperature profiles for cooling in still air or with quenching are in FIG. 3 shown.
FIG. 4 are some of the investigated experimental melts and their mechanical characteristics and cooling conditions compared to common and high strength steel materials shown. It becomes clear that the developed steel alloy encompasses the range of higher-strength materials combined with significantly improved elongation properties. The results impressively confirm the excellent mechanical properties (strength and toughness of the steel alloy according to the invention even for semi-finished products such as slabs or slabs) in the cured state ( Table 1 ).
TRIP Transformation Induced Plasticity
the stabilization of the retained austenite and the martensite start temperature are observed taking into account the cooling rate, wherein in the aforementioned.
empirically determined formulas the contents of C, Mn, Si, Al, Cr and Mo in wt .-% and ⁇ are used as the cooling rate in ° C / sec.
the units of the coefficients used in the formulas should be chosen according to the variables used in the formulas.
Martensite starting temperature (° C): In order to avoid larger martensitic microstructures which may degrade the mechanical and technological properties, the martensite starting temperature shall be determined as follows: 525 - 350 ⁇ C - 45 ⁇ Mn - 16 ⁇ Mo - 5 ⁇ Si + 15 ⁇ al ⁇ ⁇ 400
the microstructure of the steel according to the invention consists of bainitic ferrite and retained austenite lamellae. It may have fractions of up to 5% martensite (or martensite / austenite phase and / or decomposed austenite).
martensite or martensite / austenite phase and / or decomposed austenite.
the two most important parameters of the microstructure, which significantly influence the mechanical properties of the steel, are the fin spacing and the proportion of retained austenite. The smaller the fin spacing and the higher the proportion of retained austenite, the higher the strength and elongation at break of the material become.
the average fin spacing should be less than 750 nm, advantageously less than 500 nm.
a residual austenite content of at least 10% and a martensite proportion of at most 5% should be present.
the average former austenite grain size should not exceed a value of 100 ⁇ m.
the microstructure is very fine, the microstructural constituents can hardly be differentiated by light microscopy, so that a combination of electron microscopy and X-ray diffraction can be used on a case-by-case basis.
the result of an X-ray diffraction measurement is in FIG. 7 shown. From the intensity distribution of the X-ray spectrum, the crystal structure of the existing structural constituents and their phase components can be determined.
