The paper describes the development of austenitic steel with TWIP effect, which is alloyed chromium to increase corrosion resistance. experimental heat this was cast in an melting furnace and subsequently subjected hot cold rolling. After rolling, appropriate recrystallization annealing temperature applied obtain optimal grain size. X-ray diffraction proved that contains a fully structure. anne...

In recent years, TRIP/TWIP steels have been the focus of great attention thanks due to their excellent tensile strength-ductility combination. The compression tests were performed at different temperatures from 25 to1000°C to study the mechanical behavior of advanced austenitic steel with 21% manganese plus bearing Ti. The results indicated that the plastic deformation is controlled by deformat...

Twinning induced plasticity (TWIP) steels with high manganese percentage (17-35%), are mostly used in automotive bodies. Their microstructure at room temperature is austenitic, and due to the low stacking fault energy, major deformation mechanism in them is twinning inside austenite grains which leads to enhanced mechanical strength in the steel. Due to the important effect of heat treatment pr...

iii Abstract: High manganese TWIP (TWinning Induced Plasticity) steels are particularly attractive for automotive applications because of their exceptional properties of strength combined with an excellent ductility. However, as austenitic steels, they appear to be sensitive to liquid zinc embrittlement during welding, the liquid zinc arising from the melted coating due to the high temperatures...

Twinning-induced plasticity (TWIP) steel is a second-generation advanced high strength grade developed for automotive applications. TWIP steels exhibit an excellent combination of and ductility, mainly originating from the activation deformation twinning. However, generally relatively low yield (YS), which limits their practical Thus, developing YS without ductility loss essential to increase i...
