Mechanical properties of structural materials

We work with a series of advanced mechanical tests methods to determine the mechanical properties of a material. By combining these methods with microstructural investigations we can study the active deformation and damage mechanisms.

Research at IEI holds a high standard

Stanford University has recently released an updated list of the top two percent most cited researchers globally, and it is gratifying to note that once again, several distinguished researchers from IEI are represented on the list.

Organisation

Microstructure of steel.

Engineering Materials (KMAT)

The Division of Engineering Materials explore the relationships between microstructure and properties of mainly metallic materials but also ceramics, composites and polymers for engineering applications.
