This study involved the characterisation of a newly developed 9%CrMoCoVNbNB (FB2) martensitic creep resistant steel for use in large industrial turbine disc and shaft components. A major part of the work involved characterisation of FB2 with incorporation of material, thermal and physical data into a finite element-based model for the simulation of coupled thermo-mechanical working with consideration of grain size evolution based on the implementation of a user sub-routine within the FEM code (QForm). The main focus of the research was to gain a comprehensive understanding of the non-uniform temperature, strain rate, strain and grain size distributions apparent during hot open-die forging.
