Originální abstrakt

In this work, cast standard duplex steel ASTM A890 Gr4A is investigated and subjected to different isothermal annealing temperatures in the range from 600 °C to 900 °C and in the range from 1 hour to 250 hours. The change in microstructure at these isothermal annealing temperatures is mainly reflected in ferrite, which is transformed into phases such as sigma phase (σ), chi phase (χ), chromium carbides (M23C6), chromium nitrides (Cr2N), secondary austenite (γ2) and Widmanstätten austenite (γw). All phases affect not only the corrosion resistance but also the mechanical properties such as ductility and plasticity, so they cause cracks when the cast is cooling down in the mould, which we try to avoid.
