Detailed Microstructural Evolutions of TWIP Steel During Tensile Straining: In situ SEM Observations
Microstructural evolutions of twinning induced plasticity (TWIP) steel during tensile straining were investigated by in situ SEM observations. The results indicated that slip lines and mechanical twins as well as surface relief were increased with increasing strain, resulting in a stepped surface. Additionally, these deformation mechanisms could change the shape of each grain via shear and rota...
متن کاملObservation of Stacking Fault Tetrahedral in TWIP Steel
Low stacking fault energy face centered cubic (FCC) materials contain characteristic defect structures. Stacking fault tetrahedral are one of those rare structures that occur under special experimental conditions. For the first time, stacking fault tetrahedral were observed in Fe-30Mn-3Al-3Si twinning induced plasticity (TWIP) steel. Their presence resulted from a quenching heat treatment.

متن کاملTwin-Induced Plasticity of an ECAP-Processed TWIP Steel
The TWIP steels show high strain hardening rates with high ductility which results in high ultimate tensile strength. This makes their processing by equal channel angular pressing very difficult. Up to now, this has only been achieved at warm temperatures (above 200 C). In this paper, a FeMnCAl TWIP steel has been processed at room temperature and the resulted microstructure and mechanical prop...
