摘要 |
A method of producing metal sections wherein first a groove is made in a section limb by microstructure-changing deformation, then another section limb is placed in the groove and that material of the first section limb which is situated to the side of the groove is moved onto the side walls of the inserted section limb by pressure to such an extent that an at least force-fitting joint between the two section limbs is made at the contact location. This method of microstructure-changing attachment of section limbs makes it possible to produce metal sections with virtually any desired geometry and using any desired starting materials the strength of which sections is comparable to metal sections produced in a previously known manner. |
