Abstract

The methods of cold rolling of rods are widely used in manufacturing industries to obtain pieces with complex profiles. In this study, complex profiles with grooves have been formed by in-feed methods using two rolls. The microhardness has been measured by Vickers method in an axial section of the rolled piece. The process also has been simulated by means of finite element calculations using the Abaqus/Explicit code, giving the distributions of yield stress and residual stress at the end of the process. Finally, a comparison is made between experimental and simulated results.
