ABSTRACT:
Improvement in a method for producing a sintered elongated article by the steps comprising filling a metal pipe with a material powder, carrying out plastic deformation of the metal pipe and then subjecting the material powder in deformed metal pipe to sintering. In the invention, a netting of metallic wire (1) whose melting point is higher than a melting point of the material powder (3) is arranged around the metal pipe (2) before the sintering.
