Conclusions

  1. 1.

    In vacuum-melted extruded copper with fine grains or grains differing in size strong grain growth is induced by subsequent heating at temperatures above the extrusion temperature. This is responsible for the remnants of cold-drawn structure observed on diffraction patterns of rods extruded at 700°. This is not observed in rods extruded at 1000°.

     
  2. 2.

    Grain growth in fine-grained cold-drawn rods during high-temperature annealing favors the presence of the drawing texture.

     
  3. 3.

    The uneven deformation through the section was determined from measurements of the microhardness.
