説明

Residual stresses in 0.25% carbon steel and 0.45% carbon steel bar specimens which were cold drawn to cross-sectional reductions from 5 to 29% were measured. The cold drawing was carried out several times by the cross-sectional reduction of about 5% per pass. The residual stresses in the section of specimens after drawing were tensile at the outer part of the specimens, and compressive at the inner part of the specimens. The maximum residual stress at the outer part increased successively with the cross-sectional reduction to about 20%, and decreased over 20%. There are differences in the variation of the normal residual stress distribution with increasing cross-sectional reduction below and over at 20%. The textures in the outer and inner parts of these specimens were measured. The influence of the structure for the occurrence of residual stresses was discussed.
