Definitions

  • the invention relates to an Al-Cu-Mg-Mn alloy for the production of semi-finished products with high static and dynamic strength properties. Furthermore, the invention relates to a semi-finished product made of such an alloy with high static and dynamic strength properties and a method for producing such a semi-finished product.
  • Aluminum alloys AA 2014, AA 2214 which can withstand high static and dynamic loads, are, for example, die forgings for aircraft wheel and brake systems made from these AI alloys in the heat-hardened state. While the stated strength properties of the semi-finished products made from such an alloy are inherent in the semi-finished product, especially at lower temperatures, these properties decrease more rapidly at temperatures of more than 100 ° C. than in the case of alloys of group AA 2618. Semi-finished products made from such alloys have a higher Heat resistance and are used, for example, as compressor wheels for rechargeable diesel engines or for rotors in ultracentrifuges. At temperatures below 100 ° C, however, the aluminum alloys of groups AA 2014 and AA 2214 can withstand higher loads.
  • Compressor wheels have started to use titanium alloys so that the compressor wheels made from them are given the necessary static and dynamic strength properties even at higher temperatures.
  • titanium is expensive and in particular also not suitable for the production of aircraft wheels for this reason.
  • titanium is less suitable as a wheel material due to its limited thermal conductivity.
  • the alloy has the following composition:
  • zirconium (Zr) 0.1 - 0.25% by weight of zirconium (Zr)
  • the claimed alloy has a higher static and dynamic heat resistance and an improved creep resistance with very good fracture mechanical properties. These are achieved in particular with a copper-magnesium ratio between 5 and 9.5, in particular with a ratio between 6.3 and 9.3.
  • the cup The content is preferably between 3.8 and 4.2% by weight and the magnesium content between 0.45 and 0.6% by weight.
  • the copper content is significantly below the maximum solubility for copper in the presence of the claimed magnesium content. As a result, the proportion of insoluble, copper-containing phases is very low, taking into account the other alloying and accompanying elements. This results in an improvement in the dynamic properties and the fracture toughness of the semi-finished products made from such an alloy.
  • part of the claimed alloy is silver with contents between 0.3 and 0.7% by weight, preferably 0.45 and 0.6% by weight.
  • silicon (0.3-0.7% by weight, preferably 0.4-0.6% by weight)
  • curing takes place using the same mechanisms as in silver-free Al-Cu-Mg alloys.
  • the addition process is different for smaller silicon contents due to the addition of silver.
  • the semi-finished products made from such an alloy do have good heat resistance and creep resistance in cooler conditions; however, they do not yet meet the desired requirements. Only silicon contents above 0.3% by weight suppress the otherwise typical change in the precipitation behavior of Al-Cu-Mg-Ag alloys, so that surprisingly higher strength values without sacrificing heat resistance and creep resistance in the Cu and Mg contents according to the invention are achievable.
  • the manganese content of the claimed alloy is 0.1 to 0.5% by weight, preferably 0.2-0.4% by weight.
  • the manganese content is limited to 0.4% by weight.
  • manganese is an alloy component required for structural control.
  • the zirconium alloy contains between 0.10 - 0.25% by weight.
  • aluminides are even more finely dispersed than man- gan aluminides.
  • zirconium aluminides contribute to the thermal stability of the alloy.
  • titanium for grain refining, 0.05-0.15% by weight, preferably 0.10-0.15% by weight, of titanium is added to the alloy.
  • the titanium is expediently added to the alloy in the form of an Al-5Ti-1 B master alloy, as a result of which the alloy automatically contains boron. This forms finely divided, insoluble titanium diborides. These contribute to the thermal stability of the alloy.
  • the alloy can have a maximum of 0.15% iron, preferably 0.10% iron.

  • Fig. 3 a diagram showing the 0.2% proof stress and the
  • 4a, 4b Diagrams illustrating the fatigue strength of the alloy according to the invention in comparison to a previously known alloy in the state T6 at room temperature and at a temperature of 200 ° C.
  • Table 1 below gives the chemical composition of four alloys according to the invention (B, C, D, E) and the composition of the comparatively examined alloys AA 2214 and AA 2618 again (data in% by weight) (nb: not determined):
  • Semi-finished products were produced from these alloys by the process steps given below: a) casting an ingot from an alloy, b) homogenizing the cast ingot at a temperature which is as close as possible to the melting point of the alloy for a time which is sufficiently long In order to achieve the most uniform possible distribution of the alloy elements in the cast structure, c) hot forming of the homogenized ingot by forging at a block temperature of about 420 ° C, d) solution annealing of the semi-finished product formed by forging at temperatures that are sufficiently high to allow for the Bring the necessary alloying elements evenly distributed in the structure in solution, whereby the solution annealing takes place in a temperature range at 505 ° C over a period of 3 hours, e) quenching the solution-annealed semi-finished product in water at room temperature, f) cold forming the quenched halves euge by cold upsetting by 1 to 2% and g) heat-curing the quenched semi-finished product at temperatures at 170 ° C over a
  • L longitudinal direction: parallel to the main direction of deformation
  • LT long transverse direction: parallel to the width direction
  • ST short transverse direction: parallel to the thickness direction.
  • the improved strengths of the alloy according to the invention can be clearly seen from Tables 2 and 3.
  • the previously known alloy AA 2214 shows good strength values at room temperature, but not at higher temperatures.
  • the creep resistance and the fracture toughness are not only better at room temperature but in particular also at higher temperatures with the claimed alloy than with the previously known alloys.
  • This comparison also shows that the previously known alloys examined only have good properties with respect to individual strength parameters. In no case do they have good properties at all relevant strength values both at room temperature and at elevated temperatures. Just like the fatigue properties, the creep resistance of this previously known alloy is unsatisfactory. All of the strength parameters examined have very good properties and can only be determined in the alloy according to the invention.
  • alloy E alloy according to the invention
  • AA 2214 and AA 2618 previously known alloys
  • the hot-forming step is carried out at a block temperature between 320 ° C and 460 ° C.
  • the step of quenching the solution-annealed semifinished product can take place in a temperature range between room temperature and 100 ° C. (boiling) in water. It is also possible to use a water-glycol mixture for quenching, but the temperature of which should not exceed 50 ° C.
  • thermosetting can be carried out over a period of 5 to 35 hours, preferably between 10 and 25 hours, in a temperature window between 170 ° C. and 210 ° C.
  • continuous cast ingots were produced as described above and aircraft wheels were die-forged in the fore and finished dies at a temperature of 410 to 430 ° C. These wheels were then solution annealed at 505 ° C, quenched in a water-glycol mixture at room temperature and aged for 20 hours at 170 ° C.
  • Fatigue tests on comparable samples of the two alloys mentioned also show that the wheels made from the claimed alloy achieve significantly better values than those made from the wheels made with the AA 2214 alloy. This applies to fatigue tests carried out at room temperature (cf. FIG. 4a) and to fatigue tests which were carried out at a test temperature of 200 ° C. (cf. FIG. 4b).
