Herein, the effect of shortening intercritical annealing (IA) time in a two-step process “intercritical and tempering (IAT)” on microstructure mechanical properties medium-manganese steel (MMnS) made Fe–0.05C–7Mn–1.5Cu–1.5Ni–1.5Al–1.5Si–0.5Mo (wt%) containing copper-rich (CRP) Ni(Al/Mn) precipitates is investigated. The atom probe tomography (APT), electron backscattering diffraction (EBSD), sy...
A medium Mn steel has been designed to achieve an excellent combination of strength and ductility based on the TRIP (Transformation Induced Plasticity) concept for automotive applications. Following six passes of hot rolling at 850 °C, the Fe-7.9Mn-0.14Si-0.05Al-0.07C (wt.%) steel was warm-rolled at 630 °C for seven passes and subsequently air cooled to room temperature. The sample was subseque...
Abstract This contribution addresses the effect of heating and cooling rates on microstructure a double soaked medium-Mn 0.16C-5 Mn‑1.6Al‑0.2Si steel with an increased Al addition. The obtained results show that differences in applied have small investigated steel. Some dilatometer response during final to room temperature were noted. Moreover, some changes fraction retained austenite at partic...
