Center for Advanced Steels Research, CASR

CASR covers the whole chain of steel processing from raw material handling to the mechanical properties of steel and the fabrication of final product:

4

-  process control, -  process and physical

metallurgy based design, -  prediction of chemical

compositions, micro-structures and

-  the rolling stage modelling

-  modelling the relationships between industrial processing data and

-  modelling the properties of novel steel grades.
