Abstract (en)

[origin: EP0761826A2] Prodn. of seamless pipes made of materials forming a strongly elongated coarse grain structure by mechanical deformation in combination with a recrystallisation heat treatment is claimed. The novelty is that a bowl or sleeve starting part in non-recrystallised state is made by pressing according to DIN8583, T2 with a degree of deformation of at least 30%, into the required. pipe form, and the material is recrystallised by intermediate calcination between individual deformation steps or by a final calcination after the deformation.
