  • melt metallurgical and liquid phase impregnations as well as die casting techniques are generally used.
  • the long reaction and contact times of molten metallic phases with the reinforcing fibers and the molding tools or surfaces result in undesirable damage.
  • dissolution and precipitation processes as well as chemical interface reactions occur.
  • liquid, chemically highly active light metal melts (usually aluminum) are used, so that additional protection of the fibers used is essential with a suitable protective layer.

  • the process is intended to enable the most cost-effective and energy-saving production of components that are shaped close to production (net-shape molding).
  • the Thixou molding process is basically known in the prior art for forming special alloys, in particular aluminum-based or copper-based, with which a two-phase or multi-phase region is used within a specially selected temperature range above the solidus line and below the liquidus line, in which a liquid phase share is present.
  • a pronounced solidification interval of the alloy to be formed is required, ie a temperature range in which both solid and liquid phase components are present side by side (cf. FIG. 1).
  • Suitable alloy with thixoidal forming has a globolithic structure that forms a solid phase skeleton and thus ensures good handling of the heated semi-finished product when it is inserted into a press mold.
  • This solid phase skeleton breaks open under shear loads and thus reduces the yield stress, so that only short flow distances result in the tool and a near-net-shape deformation can be achieved.
  • a first advantage is that the temperature is significantly lower than the use of melt processes or melt infiltration processes and the significantly shortened molding exercise time. In this way, it is possible to dispense with the coating of the embedded fibers or particles, since the embedded fibers are hardly damaged by the only short melting process at a relatively low temperature.
  • the entire melting shop (melting furnace, alloy furnace, degassing, alloy control, casting furnace) can be dispensed with.
