Structural and mechanical properties of laboratory rolled steels high-alloyed with manganese and aluminium
The paper deals with rolling conditions, microstructure, as well as basic mechanical properties of four different high manganese steels after laboratory melting, casting, and hot and cold rolling. The stacking fault energy of heats was in the interval of 85–114 mJ m−2 thanks to the high aluminium contents. The heats with the lowest sum of (C+Mn) supported the highest ferrite volume fraction (up to 45%), while the highest sum of (C+Mn) led to 10% ferrite formation. With lower Al/(C+Mn) ratio and lower ferrite fraction higher rolling forces were necessary to be used. Due to heterogeneities of matrixes and observed aluminium oxide complexes differences in mechanical properties were detected. The best results showed the heat with 0.65% C-29.5% Mn-9.0% Al and a stacking fault energy 114 mJ m−2.
