Abstract:

The microroughness evolution of the inner surface of copper pipes under drawing is considered. The roughness parameter R (a) is measured on the internal surface of pipes after pressing and drawing. It is revealed that R (a) is minimal for hot-pressed pipes. Deformation by drawing to a logarithmic degree of deformation in 0.417 is accompanied by a rise in average parameter R (a) from 0.20 to 6.16 mu m, i.e., approximately 30 times. The highest growth rate of R (a) is noted in the early pass of drawing. The increase in the dispersion of the value measured over drawing pass is also ascertained. The resulting phenomenon is explained by the effect of the copper grain turn.
