Application of Statistical Representation of Microstructure during Simulation of Ferritic-Pearlitic Steel Wire Drawing

Abstract

Development of modelling method, which allows prediction of the properties distribution in the metal volume with the behavioral features of the microstructure under the influence of the deformation during drawing, was the objective of the paper. Multiscale model of rod drawing process was proposed. To save computing time, statistical representation of the microstructure was applied. Statistically Similar Representative Volume Element (SSRVE), representing ferritic-pearlitic steel microstructure, was developed. Simulations of the drawing process were performed, and local deformation of each structural component was predicted. Selected results, as well as discussion of the effect of microstructure on obtained stress and strain distributions, are presented in the paper.
