Hydrogen effects on the deformation and fracture of alloys

MPI SusMat Colloquium
The increasing demand on lightweight structures requires high-strength materials. However, with increasing strength many materials show an increasing susceptibility to hydrogen embrittlement. Hence, it is of vital interest to understand the mechanisms of hydrogen embrittlement. [more]
Due to its high diffusivity hydrogen atoms alloy with metals even at room temperature. At this temperature, the materials microstructure remains rather stable. When the system size is reduced to the nano-scale, microstructural defects as well as mechanical stress significantly affect the ... [more]

Sustainability and raw materials: do we have them enough?

Materials play a crucial role in driving the twin transition, a key strategy of the European Union to address current and future environmental challenges. Currently, improving the efficiency of solar cells and the capacity of battery storage is essential for achieving a Net Zero Carbon society ... [more]

Constant strain rate nanoindentation up to 10,000 s-1 for reliable extraction of mechanical properties and activation parameters

The use of nanoindentation-based techniques to study high strain rate deformation behavior of materials is of immense scientific interest because it enables investigating the strain rate dependence of individual grains and small-scale structures. While nanoindentation impact tests, capable of ... [more]

Refractory alloys and composites - pathways to improved performance

Refractory metals and their alloys are considered a versatile group of high temperature resistant materials. Promising design approaches to extend their application range include the modification of both existing commercial materials, but also novel alloys that are still at earlier stages of ... [more]

Strengthening and Toughening Mechanisms in Metal-Graphene Nanolayered Composites

Nanoscale metal-graphene nanolayered composites are known to have ultra-high strength due to the ability of graphene to effectively block dislocations from penetrating through the metal-graphene interface. The same graphene interface can deflect generated cracks, thereby serving as a toughening ... [more]
In the search for new energy sources, nuclear fusion of deuterium and tritium is one of the most promising options for human kind. However, thermonuclear fusion has set an enormous challenge to theory, experiment and technology due to the harsh environment that will take place in a future nuclear ... [more]
