Materials and Simulation 

Harnessing complexity in materials

Materials Expertise

We have more than 40 years of experience in the field of materials science, both in academia and industry. Our understanding and passion for materials will help you to trust the material in your component. 

Understand Materials

Modern applications require higher loads on the systems, pushing the material to its limits. Our material knowledge enables safe design to the load capacity limit of the material.

Discover your Atoms

Modern atomistic simulations open up the world of atomic structures to you. Discover your material on the smallest length scales and gain new insights. Use this expertise to optimize your components with less experimental effort.

Porosities in Materials

In most casting processes, pores and internal defects cannot be avoided due to the production process. Modern X-ray computed tomography can characterize these material defects on their size, shape, and geometry. This data allows the classification of the pores according to their mode of origin, such as shrinkage, gas precipitation or thermal distortion. Hence, engineers can optimize casting processes and products in a targeted manner.

High-performance materials

Fiber-reinforced high-performance concrete allows structures to be designed with significantly greater filigree while retaining the same load capacity. So material can be saved and architecturally demanding structures can be realized. The high strength is achieved, by the addition of steel fibers and a low porosity. Computed tomography enables the quantitative characterization of porosity and fiber orientation in the material. Based on these findings, concrete quality can be controlled and development loops accelerated.

Material Analysis

X-rays are attenuated as they pass matter. The ability to penetrate materials depends on the material-specific absorption coefficient and the energy of the incident X-rays. The resulting absorption contrast allows for the visualization of material phases and density differences, as shown in the image. This makes it possible to quantitatively analyze thickness and surface defects of the anodized surface layer - without destroying the component. During anodization, the part is immersed into an electrolyte bath and a direct current is passed through the medium. The electrolytic passivation forms a wear-resistant oxide protective layer on the surface.

Electronic Components

The high resolution of industrial computed tomography (iCT) enables detailed characterization of solder joints, clamping contacts or material defects in electronic components. It can also be used to examine areas that are not directly accessible. The non-destructive nature of iCT scans can be used to quantitatively assess quality before and after lifetime testing.
