Metallography of AHSS steels with retained austenite

Popis výsledku v původním jazyce

Advanced grades of high strength steels have been developed in the last decades. Several of them relay on excellent performance of controlled volume of retained austenite during plastic deformation. Retained austenite plays a crucial role in mechanical properties of these steels and therefore its volume fraction, morphology and distribution must be analysed. Two types of these steels are used in this chapter, namely multiphase transformation induced plasticity steel (TRIP) and martensitic steel obtained by quenching and partitioning (QP). Analysed samples were processed by various heat and thermo-mechanical treatments to produce higher variety of final microstructures, possessing around 10-18% of retained austenite. TRIP an QP processed microstructures were characterised by the means of light microscopy, scanning and transmission electron microscopy and X-ray diffraction phase analysis. Distribution of retained austenite was also confirmed by EBSD analysis. Colour etching was used to visualise retained austenite in TRIP steels and the amount was subsequently quantified by image analysis of light micrographs.
