ABSTRACT:
A method of producing intermetallic phases from powdery ductile components that are mixed in a predetermined mixture ratio and are subsequently precompacted by cold pressing. Subsequently, the precompacted components are pressed, via compaction, to such an extent that the degree of deformation is greater than 80%; thereafter, the thus-produced material is thermally treated.
