Abstract
We have proposed a microstructure-based multiscale simulation framework based on Integrated Computational Material Engineering (ICME) concept and applied it to the simulation of hot rolling process of a duplex stainless steel. In the study, the finite element simulation of the hot rolling process is performed. The mechanical property of a slab is calculated on the basis of its underlying solidified microstructures, which are simulated by the multi-phase field method coupled with CALPHAD thermodynamic database. The properties of constituent phases in the solidified microstructure is obtained by the first-principles calculation, the molecular dynamics simulation and nano-indentation tests. The mathematical homogenization method is used to calculate the property of slab based on the microstructure. This paper reviews the application of the multiscale simulation framework to a SUS304 duplex stainless steel.
