- Abstract
- High Mn TWIP steel is regarded as a promising material for the next generation automobile steel because of its high strength and good ductility. Most of the rolling and recrystallization texture studies of TWIP steels have been made at relatively low rolling reductions (50-60%). In this study, the rolling and recrystallization textures of 60-80% cold-rolled Fe-18% Mn-xAl-0.6% C steel with x being 0-3% have been investigated. The cc fiber connecting Goss (110)< 001 > and brass {110}< 112 > orientations in the Euler space developed in the cold-rolled sheets, whose orientation density tended to increase with increasing rolling reduction and Al content. The a fiber rolling texture transformed into the recrystallization texture consisting of the main Goss component and minor brass component after annealing for 10 min at 800 degrees C, implying that the brass orientation transformed into the Goss orientation during recrystallization. The orientation transition was discussed in terms of the strain-energy-release-maximization theory for the recrystallization texture evolution. (C) 2015 Elsevier B.V. All rights reserved.
