METHOD FOR THE PRODUCTION OF A COMPOSITE MATERIAL OR A PRECURSOR PRODUCT FOR THE PRODUCTION OF A COMPOSITE MATERIAL

摘要

The invention relates to a method for the production of a starting product for the production of a composite material having a metallic matrix phase and a reinforcement phase, with the following steps: Providing an extruder device having a die (4), Feeding the metallic matrix phase in a first portion of the extruder device, Transport of the metallic matrix phase in the direction of the die (4), Feeding reinforcement particles forming the reinforcement phase in the region of a second portion of the extruder device, Partially melting the metallic matrix phase by heating it up to a temperature between the solidus and the liquidus temperature. Producing a mixture formed from the reinforcement particles and the at least partially melted on metallic matrix phase and further transport of the mixture through the die (4) .
