JMAK model applied on the κ-carbide precipitation in FeMnAlC steels

Different lightweight steels alloys have been treated by different isothermal treatments in order to understand the basics of precipitation kinetics of κ-carbide for such class of new steel grades featured by high concentration of Mn and Al. The κ-carbide precipitation plays a significant role to induce the strengthening of these steel grades that maintain a significant ductility up to the fracture as a consequence of their duplex...
