Temperature-Effect on the Steel Wire Drawing

Abstract

The drawing of steel wire was carried out at various temperatures ranging from the room temperature to 600°C. This is possible, and the wire was protected from oxidation, being coated by the Perkarizing-process and drawn using especially soap or graphite, as the lubricant, which was found very good. By the drawing temperature, deformation is divided into three zones-room temperature zone, blue brittleness temperature zone, and recrystallizing temperature zone. Mechanical properties, distribution of fibre structures, micro- and macro-structures, and distribution of residual stresses are varied at each zone, and each deformation mechanism was discussed. Above all, mechanical properties behaves as if the one characterized at the temperature tawhich drawing is carried, is frozen to the room temperature.
