Abstract

The degree of similarity between simulated and experimental fcc rolling textures is characterized by a single scalar parameter. The textures are simulated with a relatively simple and efficient 1-point model which allows us to vary the strength of the interaction between the grains and the surrounding matrix and the scheme for the calculation of the lattice rotation. For the copper-type texture the best agreement between simulation and experiment is obtained by {111}<110> slip combined with relaxed constraints according to a procedure different from the traditional scheme for relaxed constraints. A Sachs-type model without any volume effect of deformation twins provides a very high degree of similarity between simulated and experimental brass texture. Addition of volume fractions of deformation twins corresponding to those observed experimentally has practically no effect on the simulated textures.

Highlights

The existence of two different types of fcc rolling texture, the copper-type texture and the brass-type texture, is the classical problem within the field of deformation texture
According to the predominant ideas it may be simulated by a combination of {111} slip and a volume effect of deformation twinning as originally suggested by Wassermann [2] or by {111} slip only with a special pattern of deformation and lattice rotation, e.g. [1,3,4]
In the present work we do strictly quantitative comparisons between the simulated and experimental textures via a single scalar correlation factor obtained from the procedure developed by Tarasiuk and Wierzbanowski [5]

Summary

Introduction

The existence of two different types of fcc rolling texture, the copper-type texture and the brass-type texture, is the classical problem within the field of deformation texture. As reviewed by Leffers and Ray there is general agreement that the development of the copper-type texture can be simulated by models with {111} slip. There is not a corresponding general agreement about the simulation of the development of the brass-type texture. In the present work we do strictly quantitative comparisons between the simulated and experimental textures via a single scalar correlation factor obtained from the procedure developed by Tarasiuk and Wierzbanowski [5]. This correlation factor involves all components/aspects of the textures considered. The simulated and experimental textures correspond to the reduction of 60%
