The aim of this study is to reveal how electrochemically
charged ferrite forms hydrogen-induced blister cracks. The
novelty of this research is the use of a highly brilliant neutron
beam at the new neutron radiography instrument V7
at Helmholtz-Zentrum Berlin (HZB) with the newest detector
generation that allows the detection and visualization
of hydrogen distributions with an unprecedented spatial
resolution. An extended fracture analysis adds information,
which is necessary to understand the crack initiation
and blister evolution.
