Definitions

  • the invention relates to an alloy for the production of Metal foam bodies, a process for producing the Alloy with certain additives for manufacturing of metal foam bodies.
  • Various methods for producing metal foam bodies consist essentially in that a gas-releasing blowing agent is added to an alloy powder or a powder mixture of alloy constituents, an unexpanded semi-finished product being produced first and this semi-finished product subsequently being heated to a temperature above the decomposition temperature of the blowing agent, preferably is brought to foaming in the temperature range of the melting point of the metal alloy, after which the body thus foamed is then cooled.
  • the semi-finished product can be foamed freely or in a mold, and metal foams with a density of about 0.3 to 1.7 g / cm 3 can be produced using aluminum or aluminum alloys.
  • One method of making porous metal bodies is described and exists for example in DE-40 18 360 C1 from the steps: making a mixture of at least a metal powder and at least one gas-releasing Blowing agent powder, hot compacting this mixture into one Semi-finished product at a temperature at which the connection of the Metal powder particles predominantly done by diffusion and at a pressure high enough to disintegrate the Prevent blowing agent such that the metal particles are in a fixed connection with each other and a gas-tight seal for the gas particles of the Represent blowing agent, heating the thus produced Semi-finished product to a temperature above the Decomposition temperature of the blowing agent, preferably in Temperature range of the melting point of the used Metal, then cooling the so foamed Body.
  • the uneven foam structure can indicate an uneven nucleation for the Blistering due to uneven size and distribution of the silicon particles be stirred back.
  • the in the The matrix structure of embedded silicon particles is unevenly distributed and their size and shape also very uneven.
  • the invention is therefore based on the problem in the manufacture of a foamable Metal alloy, especially an aluminum alloy, for achieving the desired one Properties to achieve a foam structure that is as uniform as possible and as possible to achieve favorable strength properties.
  • a powder mixture for the production of Aluminum-metal foam bodies which according to the invention consist of a powder an aluminum alloy, a powder made of or with nucleating, a uniform Bubbles and homogeneous foam structure causing particles with a particle size less than 30 microns and a gas-releasing blowing agent powder, preferably for nucleation an addition of evenly distributed silicon, silicon carbide, Aluminum oxide and / or titanium boride particles is added.
  • the use of a also serves to solve the problem mentioned at the beginning Powder from or with nucleating, uniform bubble formation and homogeneous Particles causing foam structure as an additive to a mixture of at least one a metal powder forming metal matrix and at least one gas-releasing Blowing agent powder in the manufacture of metal foam bodies, the powder being made from Particles can consist of silicon, silicon carbide, aluminum oxide and / or titanium boride, which have a particle size smaller than 30 ⁇ m.
  • a powder can be distributed with evenly distributed Particles of a hypereutectic aluminum-silicon alloy with a proportion of Silicon in the form of silicon primary crystals in the particles of the hypereutectic Aluminum-silicon alloy of less than 12% by weight, based on the metal alloy.
  • the very finely divided particle structure in the powder added addition, especially the very finely divided one Silicon structure is crucial for a uniform Blistering and therefore for a homogeneous foam structure, because the particles in this fine distribution, especially the Silicon primary crystals as nucleating agents for the Bubble development work.
  • the foamable aluminum alloy can be, for example, an aluminum powder alloy with a blowing agent, for example titanium hydride (Tih 2 ) and a powder of a hypereutectic aluminum-silicon alloy with a proportion of the silicon in the form of silicon primary crystals in the powder of the hypereutectic aluminum-silicon alloy act of less than 12 wt .-% based on the metal alloy.
  • a blowing agent for example titanium hydride (Tih 2 ) and a powder of a hypereutectic aluminum-silicon alloy with a proportion of the silicon in the form of silicon primary crystals in the powder of the hypereutectic aluminum-silicon alloy act of less than 12 wt .-% based on the metal alloy.
  • the mixture is filled into a mold and compacted under pressure without the blowing agent powder decomposing.
  • the primary material thus produced can then be hot pressed or hot rolled or hot extruded without foaming. If this semi-finished product is heated up to about 800 ° C
  • foam products from a Aluminum alloy is only mentioned as an example.
  • the Invention also extends to foam products from everyone foamable metal, which is a powder with nucleating Particles for uniform bubble formation and homogeneous foam structure is added.
