Summary

Pearlitic steel cords may reach a tensile strength up to 4 GPa [1]. This property is related to the process of cold drawing which reduces the size of the lamellar substructure, in proportion to the wire diameter (Embury's similitude principle [2]) and induces the formation of nanocrystalline and morphological textures.

Using a multiscale transition method [3] based on a non pile-up micromechanical model for dislocations the aim of this work is to model and simulate the draw hardening of pearlitic lamellar nanocomposite.

The multi-scale transition method is described in the next paragraph and applied to wire drawing of a pearlitic industrial steel in a third paragraph.
