A New Development in Thermo-mechanical Processing of Trip Steels
Original language description
A new strategy of thermo-mechanical treatment with continuous cooling was tested for two low alloyed TRIP (transformation induced plasticity) steels. TRIP steels are high-strength steels with good formability and ductility and this excellent combinationof mechanical properties results from fine, multiphase microstructure with about 10-15 % of stabilized retained austenite. The processing of TRIP steels typically consists of heating either into the intercritical region or above, deformation applied during the cooling from this temperature and bainitic hold at temperatures around 400 °C. The hold should ensure convenient bainite content in the final microstructure and also sufficient carbon enrichment of austenitic areas. This aim of this work is to design and test a new processing strategy in which the time consuming bainitic hold is replaced by continuous cooling. Two steels with chemical compositions typical for TRIP steels have been chosen for this experimental program, 0.2C-1.5-Mn-
