    Evaluated with a Scanning Kelvin Probe Force Microscope

## Description

- description: The monitoring of invasion/permeation hydrogen on entry/exit surfaces
    of cathodically charged SUS316 columnar crystals was conducted with a scanning
    Kelvin probe force microscope (SKPFM) under atmospheric pressure. Columnar crystal
    specimens covered with oxide films on their surfaces under room conditions were
    prepared for cathodic charging tests and subsequent SKPFM measurements. The invaded
    hydrogen on the entry surface was detected at the δ ferrite phases for 7 d after
    charging, and the trapping of invaded hydrogen at the boundaries between the δ
    ferrite and austenite matrix was prolonged for >10 d after charging. The permeated
    hydrogen on the exit surface was detected at the δ ferrite phases for 3 d after
    charging, but was not substantial at some of the δ ferrite phases regardless of
    the charging. Trapping of permeated hydrogen at the boundaries between the δ ferrite
    and some of the intermetallic precipitates was prolonged for 7 d after charging.
    The behaviors of invaded/permeated hydrogen based on heterogeneous microstructures
    are discussed to improve understanding of the hydrogen embrittlement mechanism
    in weld metals.
