Self healing in Fe-based systems: From model alloys to designed steels

When high-temperature steels are loaded under under industrially relevant conditions not only creep (i.e. a time dependent strain increase even under nominally constant loading conditions) occurs, but also local damage is formed. At relatively short exposure times quasi-spherical micron-sized cavities form preferentially at the grain boundaries...

Solid state phase transformations in steels: a neutron and synchrotron radiation study

Solid-state phase transformations in steels cover a broad range of aspects. The underlying physics behind these phase transformations usually include nucleation, diffusion, lattice reconstruction and interactions between solutes and grain boundaries and interfaces. These features and the fact that the events take place at high temperatures, in...

Self-Healing Polymer Composites

Over the past decade, many different strategies were developed to introduce selfhealing properties in structural polymer composite materials. Although many of the investigated routes show promising results on an academic scale, the first commercially feasible self-healing structural polymer composite has yet to be developed. The main objective...
