  1. 1. Modeling the microstructural evolution during hot working of C-Mn and Nb microalloyed steels using a physically based model

    Författare :Linda Lissel; Stefan Jonsson; Bertil Ahlblom; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; austenite; modeling; hot deformation; microstructure evolution; static recrystallization; dynamic recrystallization; metadynamic recrystallization; Other materials science; Övrig teknisk materialvetenskap;

    Sammanfattning : Recrystallization kinetics, during and after hot deformation, has been investigated for decades. From these investigations several equations have been derived for describing it. The equations are often empirical or semi-empirical, i.e. LÄS MER

    Sammanfattning :   This thesis contains the development of a physically-based model describing the microstructural evolution during hot deformation of microalloyed steels. The work is mainly focused on the recrystallization kinetics. During hot rolling, the repeated deformation and recrystallization provides progressively refined recrystallized grains. LÄS MER
