Design of thermo mechanical processing and transformation behaviour of bulk Si-Mn TRIP steel

The results obtained in situ neutron diffraction laboratory experiment concerning the austenite to ferrite transformation in Si- Mn bulk TRIP steel specimens, displaying the transformation induced plasticity (TRIP) are presented. The advancement of ferrite formation during transformation in conditioned austenite is investigated at different transformation temperatures and has been monitored using formation during transformation in conditioned austenite is investigated at different transformation temperatures and has been monitored using neuron diffraction method. The relevant information on transformation proceeding is extracted from neutron diffraction spectra. The volume fractions of retained austenite resulting at alternating transformation conditions were measured by neutron and X- ray diffraction respectively. The stability of retained austenite in bulk specimens during room temperature mechanical testing was characterized by in situ neutron diffraction experiments as well.
