It displays thermoCalc can be a cost-effective way to develop Fe-Mn-C-Al TWIP steel. The analysis results by thermodynamic software ThermoCalc are in good agreement with the experimental results. It can make the phase transition sequence of the solidification process change significantly, which may avoid the solidification behavior of hypo-peritectic reaction. Moreover, it was found that the carbon content has a large influence on the solidification behavior, and the manganese content also affects the solidification sequence. To prevent formation of defects and porosity during laser powder bed fusion, physics-based models have been combined to estimate the melt pool geometry, and optimise the process parameters, considering the physical properties of the material. Through this study, it was found that Fe-Mn-C-Al TWIP steel may have a solidification sequence with high crack sensitivity, belonging to hypo-peritectic steel. Moreover, a new crack prevention factor has been defined to predict the susceptibility to crack formation. Based on this, the crack sensitivity of TWIP steel is further determined.

In this study, differential thermal analysis (DTA) method was used, combined with professional thermodynamic software ThermoCalc to analyze the solidification behavior for Fe-Mn-C-Al alloys with different chemical compositions. Software piracy is theft, Using crack, password, serial numbers, registration codes, key generators, cd key, hacks is illegal and prevent future development.
However, the crack sensitivity of this new TWIP steel has not been reported yet. It has an excellent combination of elongation and tensile strength, as well as good anti-delayed fracture property. Fe-Mn-C-Al alloy is a new steel grade of TWIP steel developed in recent years.
