Sažetak
The ferromanganese TWIP steels with content of 17 to 20% of manganese are fully austentic and non-magnetic, without any phase transformation. Owing to the claiming of the twinning mechanism the TWIP-steels are able to satisfy a great number od technical requirements for production of cars of the new generation. The primary experimental results of the TWIP steels show that high and tensille strenght of 600 to 1100 MPa and extreme values of ductility at intervals from 60% to 90%. Through the method of plasma and vacuum melting there were prepared alloyed castings Fe-Mn-C. The samples with dimension od 8, 5 x 15 x 20 mm were put to plasto-metrically checking (PSCT) on the Gleeble 3500. As variables there were selected temperatures from 900C to 1100C. The tests were both continuous with the deformation e=0, 8 as discontinuous with the consecutive deformation e1 up to e3=0, 3 and with the terms between the draughts from 1 to 100 seconds.
