- this step a) uses a technique carrying out the compaction, in particular the pressurization between the core and the envelope, either at the time of their joint formation (first solution), or at the time of their initial formation as separate parts (second solution), so as to create a bond of metallurgical type between the materials constituting them, generating a good interface.
