Tóm tắt/Abstract:

Despite the existence of more than two thousands types of steels, novel steel qualities are required

for future energy storage and conversion, mechanical engineering, transport and constructions.
While the properties of novel steels may benefit from combination of different micro-structural
features, ab-initio modeling techniques as well as an atomistic understanding of alloying can
enormously accelerate and guide the entire development process. Within the realm of ab-initio
electronic-structure theory, such quantum mechanical methods allows the generation of spin-
dependent structural models, the calculations of enthalpies of formation of different phases and the
calculations of other physical properties…In this talk, I will introduce the new magnetic cluster
method which allows to clarify the microscopic origin of Cr precipitation phenomena inside
ferritic/martensitic steels that are crucial for future nuclear power reactors.
