Abstract

Microstructure control is one of the most challenging issues in forming processes. It affects the quality enhancement of the product directly. The Finite Element Method (FEM) is an appropriate approach in forming analysis which can be applied for predicting microstructure. Many studies have addressed this issue through mathematical and physical models. In addition, several constitutional equations have been developed to model parameters such as grain growth, dislocation density, and recrystallization, etc. In this article, after choosing the appropriate constitutional equations and extracting the required relationships, a subroutine in the Fortran language has been developed. In the next step a rolling process with defined conditions have been analyzed in the finite element software, and the microstructural parameters have been investigated. Then the results were compared with the laboratory data and a remarkable similarity was observed. Finally, the effect of changes in friction, thickness reduction and roller speed have also been investigated.
