Recrystallization of 30Cr2Ni4MoV ultra-super-critical rotor steel during hot deformation. Part Ш: Metadynamic recrystallization

► The kinetic equations of metadynamic recrystallization were developed. ► The grain size model for metadynamic recrystallization was proposed. ► The effects of forming parameters on the microstructural evolution were studied.
