Abstract (en)

[origin: EP0976469A2] The rod-shaped material in its entire cross sectional regions is compressed, with a permanent shaped alteration in a longitudinal direction. Expansion is then carried out under the condition, that this expansion results at least up to the partial flow of the material and at the highest, up to the reaching of equally high strains in the entire cross section and thereafter is ended.
