PING 2019 is organized with the support of funds for specific university research project SVK1-2019-002.The effect of manganese addition (from 3 to 5%) on the serrated plastic flow behavior
in medium manganese TRIP steels was investigated in static tensile tests performed in
a temperature range of 20-200°C. The Portevin-Le Chatelier (PLC) effect was observed
in a steel containing the higher Mn content. The effect of deformation temperature on
the critical strain for the serrated flow was noted. The relationships between the
manganese content, deformation temperature, mechanical properties and the
appearance of serrated flow were characterized
