Description
In order to clarify the deformation behavior of spreading in flat rolling, the compression of round wire using a cylindrical tool was carried out. In the region of compressive deformation, the material flows in mostly the width direction. The width spreading is put in order by the ratio of tool diameter to wire diameter D/d0. Depending on the larger flow resistance in the direction of the wire axis by fiber structure and residual stress, the width spreading of drawn wire is larger than that of annealed wire.
