摘要：

This study was undertaken to investigate the microstructure and mechanical properties of hot rolled Fe-13Mn-0.2C-1Al-1Si TWIP steel. Tensile tests were carried out at different strain rates to determine the Portevin-Le Chatelier (PLC) effect during deformation. Subsequently, the samples were investigated by light microscopy and SEM. The sample microstructures revealed inhomogeneous dislocation zones, deformation twinning and twin-dislocation interactions. Consequently, the PLC effect during deformation was determined to be responsible for the excellent mechanical properties of the TWIP steel.
