Název v původním jazyce

Stress-strain behaviour and softening in manganese TWIP steel tested in thermal-mechanical simulator

Popis výsledku v původním jazyce

The ferromanganese TWIP steels with content of 17 to 20 % of manganese are fully austenitic and non-magnetic, without any phase transformation. Owing to the application of the twinning mechanism the TWIP-steels can satisfy a great number of technical requirements for production of cars of the new generation. The primary experimental results of the TWIP-steels show the high end tensile strength of 600 to 1100 MPa and extreme values of ductility in the intervals from 60 % to 90 %. Castings of the Fe-Mn-Calloys were prepared by the method of plasma and vacuum melting. The samples with dimension of 8.5 x 15 x 20 mm were subjected to plastometric testing (PSCT) on the Gleeble 3500. The temperatures from 900 °C to 1100 °C were selected as variables. The tests were both continuous with the deformation e = 0.8, and discontinuous with the consecutive deformations e1 up to e3 = 0.3 and with the terms between the draughts from 1 second to 100 seconds.
