Abstract
The present invention relates to a method for producing a component of a composite material comprising a metal matrix and incorporated intermetallic phases, which method comprises providing powders of at least one member of the group which comprises pure chemical elements, alloys, chemical compounds and material composites, the powder corresponding overall to the chemical composition which the composite material to be produced is intended to have, each individual powder being different to the chemical composition of the composite material to be produced, compacting the powders, bonding the powders to one another to form a unit and thermoplastically shaping the unit.

A method for producing a component of a composite material comprising a metal matrix and incorporated intermetallic phases, wherein the method comprises:
- providing powders of at least one member from the group which comprises pure chemical elements, alloys, chemical compounds and material composites, the powders corresponding overall to a chemical composition of the composite material of the component, each individual powder having a chemical composition which is different from the chemical composition of the composite material of the component,
- compacting the powders,
- bonding the powders to one another to form a unit and thermoplastically shaping the unit, the composition of the composite material of the component being as follows:
- from 40 at % to 55 at % molybdenum,
- from 5 at % to 20 at % silicon,
- from 5 at % to 15 at % boron,
- from 20 at % to 40 at % titanium,
- from 1 at % to 5 at % iron,
- from 0 at % to 5 at % yttrium,
- from 0 at % to 5 at % hafnium,
- from 0 at % to 5 at % zirconium,
- from 0 at % to 5 at % niobium,
- from 0 at % to 2 at % tungsten,
- and unavoidable impurities.
