Prior microstructure modification and synergic effect of deformation in TRIP steel
Original language description
The paper presents results of in-situ neutron diffraction experiments aimed on monitoring the phase evolution and load distribution in TRIP steel when subjected to tensile loading. Tensile deformation behaviour of TRIP steel with different initial microstructures showed that the applied tensile load is redistributed at the yield point and the harder retained austenite (Fe?) bears larger load then ferrite (Fe?) matrix. After load partitioning is finished, macroscopic yielding comes through simultaneous activity of the martensite transformation (in the austenite) and plastic deformation process in ferrite. The steel with higher volume fraction of retained austenite and less stronger ferrite proved to be a better TRIP steel with respect to strength, ductility and the side effect of the strain induced austenite-martensite transformation. The neutron diffraction proved to be efficient method to evaluate deformation behaviour of steel of different initial structures. The results have shown t
