The effect of strain induced ferrite transformation on the microstructural evolutions and mechanical properties of a TRIP-assisted steel

Thermal stability of an ultrafine-grained dual phase TWIP steel

“…Texture analysis was carried out using electron backscatter diffraction (EBSD).The conventional steps were followed for EBSD measurement sample preparation. Fine polishing was done with a 0.25 µm, self-lubricating, properties of different materials have been thoroughly explained and discussed elsewhere [39][40][41][42]. As is well established the SPT shear stress (IJ) and the normalized displacement (į) are calculated using the following equations:…”

Hot deformation characterization of duplex low-density steel through 3D processing map development

“…The various generations of advanced high strength steels (AHSS) developed over the years mainly derive a benefit from transformation induced plasticity (TRIP) and\or twinning induced plasticity (TWIP) effects to have an acceptable combination of strength and ductility [1][2][3][4]. A more recent approach to increase the specific strength of these steels is to reduce their density by adding some light-weight elements such as aluminum [5,6].…”

Effect of critical temperatures on microstructures and mechanical properties of Nb–Ti stabilized IF steel processed by multiaxial forging

“…Therefore, improvement of the YS is due to the formation of finer ferrite grains and the large size grains are responsible for retaining the ductility. Bodin et al [29] ferrite transformation was also reported to enhance mechanical properties in a TRIP steel deformed just below Ac 3 temperature [32]. Intercritical deformation followed by quenching and partitioning of a HSLA steel resulted an ultrahigh YS with a significant ductility due to the…”
