Název v původním jazyce
The influence of elevated and reduced temperature on the mechanical properties of Fe-Al-Mn-C steels
Popis výsledku v původním jazyce
The paper presents the results of mechanical properties tests at reduced and elevated temperature after a four-stage hot-rolling and cooling in water, microstructure tests and fractographic studies of breakthroughs of high-strength high-manganese steel X98MnAlSiNbTi24-11 and X105MnAlSi24-11 TRIPLEX type. In order to determine the mechanical properties of the tested steels, a static tensile test was performed, on the basis of which the yield strength, tensile strength and elongation were determined. Structural investigations using light microscopy and scanning electron microscopy enabled the identification of austenitic-ferritic structure in steels numerous deformation twins in austenite grains. Diffraction in SEM was also used to analyse the structure. The obtained test results allow assess the influence of reduced and elevated temperature on the strength properties of the tested steels. The test steels Fe-Mn-Al-C achieve very good strength properties at relatively high elongation at low temperature -70 oC. (C) 2018 TANGER Ltd., Ostrava.
