文摘

Abnormal grain growth (AGG) occurs in Eurofer-97 steel deformed to several strains. Kinetics of abnormal grain growth has been determined at 750 and 800 °C. Significant changes in crystallographic texture take place during AGG. Grain boundaries with misorientations above 45° may explain abnormal grain growth. Local microstructural instabilities (coarsening of M23C6 carbides) also explain AGG.
