| dc.description.abstract | This research work studies the effect of microalloying elements such as Nb, V and Ti on the hot flow behavior of high-Mn austenitic TWIP steel. For this purpose, isothermal uniaxial hot compression tests were carried out at three temperatures (900, 1000 and 1100 1 C) and four constant strain rates (10 1 , 10 2 ,10 3 and 10 4 s 1 ). Experimental results revealed that hot flow curves of microalloyed TWIP steels show single peak curves for all test conditions. Results are discussed in terms of the peak stress ( s p ) and peak strain ( e p ) and its dependence on the strain rate ( _ e ) and temperature. The addition of microalloying elements such as Nb, V and Ti in TWIP steels generates a slight increase in the s p value, and Ti microalloyed TWIP steel exhibits the highest s p value. Hot deformed microstructures were analyzed by the Electron Back-Scattering Diffraction Technique (EBSD). The most important results of the austenitic recrystallized grain refinement were obtained for V and Ti microalloyed TWIP steels. |
