Effect of Strain Path on Texture Evolution in Cold Rolled Pure Titanium

Abstract

The cold rolling texture evolution as a function of strain path in pure titanium with initial typical recrystallized texture has been studied using viscoplastic self-consistent simulations. Three different strain paths, namely unidirectional rolling, two-step cross rolling and multi-step cross rolling have been employed to investigate the effect of strain path change on the evolution of deformation texture. The simulation results indicate that the activation of predominant prismatic slip in unidirectional rolling sample results in the formation of commonly cold rolling fiber texture RD//<10-10> in pure titanium, whereas the increased activity of basal slip over that of prismatic slip is responsible for the strong ND//<hkil> fiber texture in the two cross rolled samples.
