Abstract
Subject headings
Close
- The use of computational quantum mechanics for the theoretical modeling of material properties of steel was described. Steel properties depend on the microstructure formed during the manufacturing process as well as on the concentartion and distribution of alloying elements and impurities. The computational methods allows reserachers to separate the effect of alloying elements on physical and chemical properties and to map the compositional distribution into the property distribution with arbitrary accuracy. The computational material design approach based on quantum theory with thermodynamics constitutes a profound advance in the design process of industrially relevant materials.
