    Effect of Deformation Conditions on Microstructure and Mechanical Properties of Low All-oyed Steel

  • Original language description

    Low carbon, low alloyed steel 0.2%C-1.8%Si-1.5%Mn-0.06%Nb underwent thermo-mechanical processing routes typical for TRIP (transformation induced plasticit) steels. Deformation conditions were varied, i.e. various num-bers of deformation steps of the same size were applied to the steel during the cooling at 50 °C/s to room tempera-ture. This processing enabled comparison of recrystallization ability of the steel at various deformation tempera-tures. In the next step, two 10% deformations were carried out at the temperatures of 900 °C and 720 °C and the deformation rate was varied from 0.025 s-1to 2.5 s-1to evaluate the effect of deformation rate on the final microstructure and properties of TRIP steel. In this case, tow-step thermo-mechanical treatment was used with additional 600 s hold at a coiling temperature of 425 °C. Final microstructures were analysed by lightand scanning electron microscopy and mechanical properties were measured by tensile test of small samples. Ultimatetensile strengths in the region of 800 MPa – 1050 MPa were achieved with accompanying total elongation of 5-37%.
