Definitions

  • the invention relates to an Ag-free Al-Cu-Mg-Li alloy and an alloy product produced therefrom.
  • High-performance aluminum alloy components are an indispensable component of aircraft design in many cases. Components of such high-performance aluminum alloys are used among other things in the fuselage and in the wing as structural components. These parts are extruded and / or forged parts. These must meet the necessary combination of static and dynamic strength and have certain requirements in terms of tensile strength, yield strength, elongation at break and crack toughness (K 1C and stress corrosion cracking). In addition, the weight plays a not insignificant role in components used in the aerospace industry. Thus, the specific gravity (density) of the high performance alloy used is also relevant.
  • a conventionally used Al-Cu-Zn-Mg alloy which satisfies these requirements is the aluminum alloy AA 7449.
  • This prior art alloy has a composition of 1.4-2.1% by weight of Cu, 1.8. 2.7% by weight Mg, 7.5-8.7% by weight Zn, max. 0.2% by weight of Mn, max. 0.12% by weight of Si, max. 0.15 wt .-% Fe and max. 0.25% by weight of Ti + Zr.
  • the components made from this alloy have a density of about 2.85 g / cm 3 .
  • Al-Cu-Zn-Mg alloy that meets these requirements is the aluminum alloy AA 7050.
  • This prior art alloy has a composition of 2.0-2.6 wt.% Cu, 1.9. 2.6% by weight Mg, 5.7-6.7% by weight Zn, max. 0.10% by weight of Mn, max. 0.12 wt .-% Si, max 0.15 wt .-% Fe and max. 0.06 wt% Ti and 0.08-0.15 wt% Zr max. 0.06 wt.% Ti.
  • the components made from this alloy have a density of about 2.83 g / cm 3 .
  • Al-Cu-Li alloys which have comparable strength values as the alloy AA 7449 and AA 7050, but the specific weight of components made from them is approximately 2, 7 g / cm 3.
  • the aluminum alloy AA 2050 is an example of such a high-performance alloy, which often replaces components that were previously produced from the AA 7449 alloy in the aerospace industry.
  • the alloy AA 2050 has a Cu content of 3.2-3.9% by weight, a Li content of 0.7-1.3% by weight and a Mg content of 0.1-0, 5 wt .-% on.
  • Zn is usually involved in the construction of the alloy with up to 0.25 wt .-%.
  • silver is alloyed in this alloy in amounts of 0.2-0.7% by weight. This measure accounts for the prevailing opinion that silver is a necessary alloying component especially in lithium-containing Al-Cu alloys for achieving high strengths of components made therefrom.
  • An alloy with an even higher Li content similar to the AA 2050 alloy, is the alloy AA 2196 with a Li content of 1.4-2.1% by weight.
  • the Cu content of this alloy is slightly reduced compared to the Cu content in the 2050 alloy. From this alloy, however, only components with lower fracture toughness and stress corrosion cracking can be made compared to components that can be made from the AA 2050 alloy.
  • the present invention seeks to provide an Al-Cu-aluminum alloy, with which high and very high strength components can be produced, and a product made therefrom, in particular suitable for use as a component in an air or space technology application, which not only meet the set strength requirements, but also the opposite made of the AA 2050 alloy components are more cost-effective in the use of materials.
  • unavoidable impurities may be contained per element of 0.05% by weight, the total amount of impurities should not exceed 0.15% by weight. However, it is preferred to keep the impurities as low as possible, so that they do not exceed a proportion of 0.02 wt .-% and a total amount of 0.08 wt .-% per element.
  • Components with very high-strength properties can only be produced within the narrow limits of the claimed alloying elements using an otherwise customary heat treatment method.
  • the aging is carried out to set maximum strengths in the component made of the alloy.
  • the usual method of thermal aging is considered to be one in which the thermal aging is carried out between 145 ° C and 170 ° C with an adapted hot aging time between 10 h and 90 h.
  • This alloy is characterized by particularly narrow bandwidths in the proportions of the alloying elements. Apart from this, the alloy is Ag and Zn-free, although a certain Zn content can be tolerated. It was just against the background of the prevailing opinion that the necessary strength could only be achieved with a Li-containing Al-Cu alloy in the components produced from it, if silver was not insignificant proportions is added surprisingly, that a manufactured from the alloy according to the invention component not only meets the requirements of the possibilities of the alloy AA 7449 strength requirements, but even against this and the alloy AA 2050 has increased strength properties.
  • the targeted narrow range of contents of the alloying partners provides an Al-Cu-Mg-Li alloy from which ultra-high-strength components can be produced.
  • a component has extremely strong properties if the yield strength R p0.2 is at least 600 MPa.
  • a component is said to have high strength properties if the yield strength R p0.2 is at least 500 MPa.
  • the Cu content is less than 3.5% by weight, the necessary strength does not arise in combination with the other alloying elements. Copper contents above 4.3% by weight in the alloy are unable to further increase the strength of a component made from the alloy. Rather, it is to be expected that at higher Cu contents. Phases develop that could damage the fracture properties and fatigue behavior.
  • Lithium is included to reduce the density (specific gravity) in the alloy.
  • the lithium content is adapted to the Cu and Mg contents of the alloy in such a way that as much lithium as possible is incorporated into the alloy, but only so much that it is brought into solution and no unwanted Li-containing phases arise. Therefore, the Li content of the alloy is limited to the narrow range between 0.8 and 1.3 wt%.
  • Magnesium contributes to the desired properties of a component made of the alloy, but is only allowed in one part, so that no unwanted phases (such as the S phases Al 2 CuMg) are established. Taking into account the other alloying elements should the Mg content not exceed 0.8 wt .-%.
  • Titanium is alloyed to fine-tune the cast and zircon to prevent / inhibit unwanted recrystallization during hot working.
  • Components made of this alloy are already cheaper because the alloy is Ag-free.
  • the cost of using the material to make the alloy can be up to 30% and more less than the corresponding cost of a comparative alloy containing Ag.
  • the specific gravity of a component made from this alloy is about 2.7 g / cm 3 for a typical alloy composition and thus corresponds to the specific gravity z.
  • a made of the alloy AA 2050 component As a made of the alloy AA 2050 component.
  • the components produced from this alloy the same weight-reducing advantage, as this also components that z. B. made of the alloy AA 2050, is awarded.
  • Fe can not be completely avoided as a companion element.
  • contents between 0.02-0.035% by weight are tolerable.
  • alloys according to the invention and comparative alloys were melted and cast on a laboratory scale into random billets by chill casting.
  • the molten alloys have the following composition, wherein the alloys XL21, XL29 alloys according to the invention, while the other alloys have been melted as comparative alloys: alloy Cu Li mg Mn Ti Zr Si Fe Ag Zn XL21 3.87 0.97 0.46 0.17 0.05 0.10 0.02 0.027 ⁇ 0.02 ⁇ 0.02 XL29 4.1 0.95 0.47 0.17 0.04 0.11 0.03 0.03 ⁇ 0.02 ⁇ 0.02 AA 2050 3.72 0.94 0.31 0.38 0.04 0.092 0.04 0.063 0.491 ⁇ 0.02 AA 2196 2.61 1.6 0.37 ⁇ 0.02 0.05 0.11 0.02 0.03 0.3 ⁇ 0.02 AA 7449 1.62 ⁇ 0.02 2.45 0.15 0.02 0.10 0.04 0.09 ⁇ 0.02 7.7 AA 7050 2.24 ⁇ 0.02 2.17 0.08 0.03 0.11 0.06 0.09 ⁇ 0.02 6.4
  • the cast ingots were homogenized and extruded or forged and then solution annealed as profiles, stretched (2 - 4% in the longitudinal direction) and warmed up.
  • the yield strength R p0.2 the tensile strength R m , the elongation at break A 5 and the fracture toughness K 1C .
  • the tests were carried out on the specimens on specimens of extruded rods in the same places.
  • a manufactured from this alloy component is due to the above-described properties as a component for use in the aerospace industry, especially for structural components. However, components made of this alloy can also be made and used for other applications, especially if a low density should also play a role.
