Coiling simulations of medium-Mn sheet steels using dilatometry
IOP Conference Series: Materials Science and Engineering, 2020 Abstract The work presents the results of coiling simulations of two medium manganese steels containing 3 and 5% Mn. The steels were subjected to the heat treatment including an austenitization at 1000°C for 300s and next isothermal holding at temperatures of 750, 700, 650 and 500°C for duration of 5 hours.
