Özet

TWIP steels are a family of high-Mn austenitic steels having both high strength and high ductility used as automotive-body steels. In the present paper, the effect of an addition of Mo on the improvement of the mechanical properties of a TWIP steel (Fe-33Mn-3Si-2Al) is investigated. Different amounts of Mo were added to the chemical composition of the steel and the resulted mechanical properties, microstructure and crystallographic phases were examined after the casting, hot rolling and annealing. The results showed that an addition of Mo enhances the mechanical properties; however, the optimum strength was obtained with an addition of 1.3 % Mo. This resulted in an increase in the ultimate strength and elongation of the steel.
