  4. Abstract:
  5. In this work, cold rolling behavior of stainless steel 304L is investigated and the effects of different process parameters on the occurrence of strain-induced martensite and mechanical properties are studied. The rolling experiments are conducted under different rolling speeds and reductions in which a set of samples is deformed at room temperature and the other set is first cooled to the temperature of − 10 °C and then rolled. Afterward, the developed microstructures and mechanical properties of the rolled steel are evaluated employing different testing techniques. In order to justify the results, mathematical modeling of cold rolling operation is also performed using Abaqus/Explicit to estimate the distribution of equivalent plastic strain and temperature rise during rolling. The results show that strain-induced martensite may occur during cold rolling and it efficiently alters microstructure and mechanical performance of the rolled plate. The amount of reduction, initial temperature, rolling layout, and, to a lesser extent, rolling speed can affect the kinetics of martensite transformation as well as microstructure and mechanical properties of the rolled steel. © 2018, ASM International
