On the Stretch-flangeability of High Mn TWIP Steels
TL;DR: In this paper, hole expansion properties of a high Mn fully austenitic twinning induced plasticity (TWIP) steel are compared with three other types of single-phase sheet steels.
Journal ArticleDOI
Effect of N on Microstructure and Tensile Behavior of TWIP Steel
TL;DR: In this paper, the effect of nitrogen and manganese on the microstructure and mechanical properties were investigated by X-ray diffraction, optical microscopy, scanning electron microscopy and tensile testing.

Evaluation of Stored Energy in Cold-Rolled IF Steels from EBSD Data and Its Application to Recrystallization Modeling
Shi-Hoon Choi,Kwang Geun Chin +1 more
TL;DR: In this article, the orientation-dependent stored energy of deformed grains from the data measured using electron back-scattered diffraction (EBSD) analysis was evaluated for static recrystallization of cold-rolled interstitial free (IF) steels.
