Abstract
High strength and ductility of the transformation-induced plasticity (TRIP) steels is attributed to the transformation-induced plasticity effect resulting from the strain-induced martensitic transformation of the retained austenite in the multiphase (ferrite, bainite) microstructure. This paper reports the results of in situ neutron diffraction experiments focused on monitoring the evolution of the phase fractions and phase stresses in three different TRIP steel samples subjected to tensile loading at room temperature.
