(European Synchrotron Radiation Facility) Researchers from the United Kingdom and France have revealed how a growing crack interacts with the 3-D structure of stainless steel.

By using a new technique at the ESRF, they could determine the internal 3-D structure of the sample without destroying it.

Afterwards, they initiated a crack and studied how it grew between the grains. The results could be useful to make more performing materials for, for example, safer power plants.
