New thermomechanical strategies for the production of high strength low alloyed multiphase steel showing a transformation induced plasticity (TRIP) effect

摘要

Carbon manganese steel with 0.16% C and 1.4%Mn, without silicon and without aluminium. Thermomechanicalpath consisting of hot rolling, batch annealing, cold rolling andcontinuous annealing combined with hot-dip galvanizing. Effectof additional step of batch annealing on manganese behaviour.Hotdip galvanizability. Scale defects. Metallurgical effects.Presentation of mathematical tools for the prediction ofmicrostructure. Mechanical properties. Verification by industrial trials.
