Obiettivo Grain refinement is the only strengthening mechanism that adds both strength and toughness to the steel. The thermo-mechanical control process (TMPC) which control grain size by a controlled rolling and an accelerated cooling is, however, not always applicable for heavy products. To overcome this problem an intragranular ferrite nucleation potential of microalloy carbonitrides can be utilised. In this work the enhancement of ferrite nucleation on carbonitride particles, predominantly VN, precipitated in austenite during finishing rolling or slow cooling after rolling, will be examined as the method for improvement of both strength and toughness for thicker plates and heavy beams. Isothermal and continuous thermo-mechanical treatments will be performed to elucidate the kinetics of M(C,N) precipitation in austenite. The output from this project will include new hot rolling practises for thick plates and heavy long products for achieving maximum grain refinement by enhanced intragranular ferrite nucleation.
