Hydrogen‐Assisted Fracture of Iron‐Based Fe–Ni–Al Alloys

Advanced Engineering Materials, EarlyView.
Principal relations and fracture mechanisms of single‐phase and precipitate‐strengthened Fe–Ni–Al alloys subjected to prior electrochemical hydrogen charging are identified. The mechanisms of hydrogen effect on strength and microhardness are discussed, including hydrogen‐induced increase in microhardness and the role of hydrogen in fracture behavior ...

Surface nanostructuring of titanium alloy dental screws by 10 keV Ar+ irradiation

Results in Surfaces and Interfaces
The influence of 10 keV Ar+ ion irradiation on the surface topography of Ti–6Al–4V dental screws was investigated. The surface facing the ion beam became uniformly covered with nanoprotrusions, the size of which increased with the ion fluence.
