Abstract Scope |
In this work, the phase transformations were studied during the intercritical treatment in a TRIP steel with chemical composition of Fe-1.39Si-2.57Mn-0.17C. Steel specimens were heated in the intercritical region, ferrite and austenite, at 750 ° C for 30 min, quenched in water without agitation, and normalized by air cooling. Microstructural analysis was performed by optical microscopy, and scanning electron microscopy, and by X-ray diffraction. All samples were mechanically characterized by uniaxial tension and Rockwell tests. Microstructural and phase analysis was also carried out with the Thermo-Calc software. The microstructural characterization results showed that the phases and microconstituents were ferrite, austenite, cementite, and austenite, Thermo-Calc results are consistent with the phases and microconstituents found for each heat treatment condition. On the other hand, the results of the tension test showed that the yield strength and ultimate tensile strength are between 763-817 MPa, and 1196-1255 MPa, respectively, for these steels. |
