Abstract. High-Mn steels have great plasticity when subjected to deformation due TWIP or TRIP effects. This work evaluated the microstructural evolution, formation of -Martensite phase taking into account hot rolling 80-60% and solution annealing. Afterwards, microstructures were analyzed by SEM. Volume fraction Austenite phases measured EBSD technique. The steel obtained low energy levels sta...

The energy required for joining steel segments by using laser welding is relatively very low compared with arc welding, gas or any other conventional techniques. Moreover, the rapid cooling may create a significant effect on different regions, such as fusion zone (FZ), heat affected (HAZ), and base metal (BM), in turn affect parameters. In this study, characteristics of laser-welded joint were ...

Abstract: In the present investigation, the effects of thermomechanical processing parameters and the steel chemical composition on the ultra fine ferrite formation characteristics were studied. This was programmed relying on the capabilities of strain induced transformation (SIT) phenomenon and applying to different grades of Si-Mn TRIP (Transformation Induced Plasticity) steels. According...
