Definitions

  • the present invention relates to a creep resistant magnesium alloy.
  • Magnesium containing metal alloys are widely used in the automotive, electronics, aerospace, and other engineering industries.
  • such alloys are advantageous, which are high temperature creep resistant and therefore can be used in a high temperature environment.
  • magnesium alloys have already been developed and standardized, such as the magnesium alloys JIS H 5203 (MC1-MC10) and JIS H 5303 (MDC1A, MDC1B).
  • alloy A developed by Dow Chemical of composition Mg-4% Al-2% SE (SE - rare earth elements) is also well known.
  • the DE 44 46 898 A1 discloses creep resistant magnesium alloys containing: 1.5 to 10% by weight of aluminum (Al), less than 2% by weight of rare earth elements (SE), 0.25 to 5.5% by weight of calcium (Ca) and magnesium In addition, the alloy may contain 0.2 to 2.5% by weight of copper and / or zinc.
  • the DE 22 01 460 A1 also discloses creep resistant magnesium alloys containing aluminum and optionally another element selected from calcium, zirconium, titanium, silicon, strontium, yttrium, cerium or barium. A combination of barium and calcium as additional elements is not disclosed.
  • the object of the present invention is therefore to provide a magnesium alloy, with which the disadvantages of the above-mentioned prior art can be overcome and also has a higher creep resistance.
  • the object is achieved by a magnesium-containing metal alloy or magnesium alloy, based on the total weight of the alloy 1 to 9 wt .-% aluminum (Al), 0.5 to 5 wt.% Barium (Ba), 0.5 to 5 wt % Calcium (Ca) as well as magnesium (Mg) and unavoidable manufacturing impurities as balance.
  • the unavoidable manufacturing impurities are present in a total amount based on the total weight of the alloy of not more than 2% by weight.
  • the proportion of aluminum is preferably 2 to 7% by weight, more preferably 3 to 6% by weight.
  • the proportion of barium is preferably 1 to 4% by weight, more preferably 1.5 to 3% by weight.
  • the proportion of calcium is preferably 1 to 4% by weight, more preferably 1.5 to 3% by weight.
  • the magnesium alloy according to the invention may additionally contain zinc, tin, lithium, manganese, yttrium, neodymium, cerium and / or praseodymium in proportions of in each case up to 7% by weight.
  • the magnesium alloy of the invention has a variety of applications; preferably, it can be used for the manufacture of components of automobiles, ships and / or aircraft, more preferably for the production of drive trains or their components.
  • FIG. 1 shows the creep deformation as a function of time at an applied stress of 80 MPa and a temperature of 200 ° C of two magnesium alloys (ABC alloys) according to the invention containing about 4 wt.% Aluminum, about 2 wt.% Barium and about 1 % By weight of calcium (ABC421) or about 4% by weight of aluminum, about 2% by weight of barium and about 2% by weight of calcium (ABC422) in comparison to the conventional alloy AE42, where E stands for rare earth elements, or an alloy with the designation MRI230D the company Dead Sea Magnesium, which contains in addition to aluminum and calcium Seltenderdmaschine.
  • the alloys according to the invention have a significantly lower creep deformation than the respective comparative alloys. It follows that you can either increase the temperature at constant voltage or that you can load a component much longer.
